Hi, i just bought a 89 240sx, it has 122k miles on it, it Automatic, it worked fine for about 2 weeks, i bought it on Nov. 22nd, 04. I wanted to do a burn out, but i had the grear on "2" by accident, i held the break down and reved my car, the car didnt move or burnout, then i noticed the gear, and i thought i put it in Drive, but it I put it in Neutral, reved up, then i was like, for get it, lets go get some gas, cus my car was almost on empty, i turned my car around and it stalled! I tried to turn it on, it wont, so I call Kyle over, and he unplugs my Fule pump fuse, and trurned it on till it worked. The car was idleing at 1500, so we drove it to his house, and Kyle and his dad, put back my stock air intake, " i had an aftermarket air filter" they said the their was a Sensore not bluged in, and the aftermarket part doesnt have the Sensor in it. Next day i drove it to work, it ran fine, on my way home, it wanted to stall at a stop sign, and when i first press the gas, it acts like it wants to stall, then, i drove it to a gas station, filled up gas, and it didnt start, i called my brother over, he tried, nothing, i bought this fule intake cleaner for like $1.50 form the gas station, and i put in in my gas tank, the car is still not turning on, it wants to when i turn the key, but it doesnt. I left the car at the gas station over night, next day the car worked, its been working.

I took the car to Nissan, they said i need this :
1.) Car has bad Temp Sensor Connector ( Corroded ) repair - $78.00

2.) Bad AIV Valve, Box, and Hose - $372.00

3.)Bad Air Flow Meter - $568.00

4.)Tuneup w/ NGK PLugs - total of $55.00 for spark plugs, wiers, and
smthing els - 149.95

My car doesnt move as fast as it did, and i had a 100lb sand bag in the trunk, befor i tried to do the burn out.
I NEED HELP!

sounded like a bad MAF to me, or a Bad aiv. valve. you can buy a used MAF at a junk yard for a fraction of the price and install it yourself. i bought my 300ZX MAF for only 100 bucks.

MAF? i have no idea what that is, sry, i dont know cars at all, i just need help!

i wouldnt recommend doing burnouts in an old ass auto 240. Something is bound to break. Did you say you were doing neutral drops???? i strongly dont recommend that. Just start fixing everything they said one by one...if the problem goes away then you dont have buy everything they said.

"i got 99 problems but a bith aint one...hit me :P

doesnt sound like the burnout had much to do with any of the problems the nissan stealer diagnosed. a maf is a mass airflow meter (sensor), that lets your ecu know how much air is flowing into the engine so it will know how much fuel to add to the mixture. the no start problem could be due to that. the high idle is probably the AIV (Air Idle Valve). search ebay or local junk yards for either, prices from dealers are ridiculous. both are quite easy to install

Aiv, can I install it my self at home?

One more thing, the previous owner of the car had an aftermarket Air intake, and some aftermarket lil inake thing AIV, so it was not connected to the Air filter "the aftermarket one", and he had shortend the length of the pipe that was comming form the AIV to the stock air intake, now i have a peice of thick rubber connecting my stock air inake and the AIV.

when im at a stop sign, or a red light, my car idles at 500, then it jumped to 600 - 700, then goes down, then it goes to like 900 - 1000, and when i turn the heat off it goes to 500 - 700 i dont even feel the car running...

befor i had all my problems my car was fast, it would pick up fast and go, but now it seems slow!

What is Seafoam, and what can i use it for?

Get rid of the AIV. All it does is cause problems. Try cleaning the MAFS with a q tip and rubbing alcohol. Be very gentle when you do. Better yet, just spray some carb cleaner on the two prongs. Try wiggling the connection to the MAFS as well.

www.240sx.org has a lot of write-ups that could help you.

Remove the AIV!!! dont i need that to bring "hot air" from the exhaust back to my engine to warm up smthing?

but if i dont need it, how do i remove it?

and can some one tell me what Seafoam is? please!

i have an 89' and it is doing the exact same thing, not as bad as yours though, im taking it into auto tomorrow hopefully i can figure out what is going on then ill tell you, does yours dip into 500 rpm when you break hard easier than if you slow to a stop? thats when mine does it, it has stalled once, but started right back up, im just taking it REALLY easy for now.

yes, my car does the same thing, ill be looking forward to see what your mechanic says about it, i took mien to Nissan, they said $1200.00!!

should i order the AIV Valve, Box, and Hose, and the MAF, or clean them?
and what about my temp sensor?

Try cleaning them. What if your bill is only $10 for carb cleaner, rubbing alcohol, and Qtips? Much better than $1200 huh? Temp sensor you can test with a multi-meter. Read the 240sx FAQ for resistance of the sensor.

ill try that, thanx

k, i just took my air filter box apart, and their is a lot of black crap on the filter, it look like its comming from the AIV, because all that dirt is right under the hole of the aiv hose.

i have and after market filter, it does not have an air flow sensor tho, what i do?

how does it not have an air flow sensor??
the mafs isnt ON the filter, its AFTER the filter.. the outside probably looks like a little black box.. about the size of a cell phone..(yeah thats not very descriptive but i can't think of anything the same size at the moment..)

how about the size and style of older box type motorola phones lol

k, here is some pics

their is also a nothor sensor in the metal part of the intake

i tried cleaning the filter, i washed it in the sink with watter, can i use anythig els, its not getting any better!

haha throw that filter out!!! its toast!! you can use it as toilet paper now!
you need a new one.. thats brutal.. and clean your aiv

will, i have an aftermarket air filter, but, it does not have hose plug for the aiv, its just like a filter!

can i use that, instead of the stock crap, even tho the AIV doesnt connect anywhere, i have a little filter thing that goes on the aiv too, it looks like an air filter, but thats as black as the stock air filter " used to be red", the previous owner had those 2 filters installed

what do you mean?? you have a filter but it has no plug?? no filter has a plug.. is it a cone filter? is the smaller one a cone filter? i have the feeling that you're talking about an aftermarket cone.. which needs to be installed. but then again i really can't tell.. be a little more descriptive.. which 2 filters did the previous owner have installed?

their is also a nothor sensor in the metal part of the intake

If it is on the engine side of the throttle body, it is the Throttle Position Sensor(TPS). www.240sx.org is going to have just about everything you need to know about tune-up stuff in better works than we can put it in.

air filters

http://files.automotiveforums.com/gallery/watermark.php?file=/501/271918Image044-med.jpg

Hey, D-Bo, looks like the little filter that's on your car.

i think its the exact same thing..
hanster, whats your intake setup right now?? is it all stock? or did you want to add those two filters?

i want to add the filters

k, their installed, my car seems to want to stop running when i first start it, it idles at 490 - 550 rpms, but after i drive it or let it run for about 10 min, its fine, before the aftermarket air filter and the AIV filter, it didnt do that when i started it, it would want to stop or act like it want to turn off when ever i stop at a light / stop sign...
and the throttle feels diffrent, i dont get as much go as i did b4

i also cleaned the MAFS with a q-tip and alcohol

i want to clean the aiv, but how do i do it?
and would i notice that its clean, even tho it dont plug into my air intake any more!

I Need Help, My Car Wants To Stop Every Time I Stop On A Stop Sign, it would idle at 500 rpms, then go up to 900 - 1100, the quickly back down to 500 and it feels like it wants to stop.

I'm having the same problem... but mine is cooling system related... stupid leaking water pump. Not that it's your problem but you might want to look other places that air intake, fuel, and emissions control.

i just installed aftermarket Air filter for air intake and the AIV, and i also cleaned the MAFS with alcohol, but the air filters and the alcohol didnt seem to do anything.

i dont know what to do, my car has no leaks, i mean i dont see any spots of anything under it.

Try wiggling the MAFS connection. Just go through the 240sx.org FAQ. It has to be something in there.

This reminds me of initial d when iggy got the 85 single overhead cam levin. Hanster24, I'm not being mean but why the single overhead cam KA. Less power. Maybe someone researched head swapping or something like that. That sucks but anyway, you can still turbo it at least. www.KA-T.org (http://www.KA-T.org) has a section for you in their forums.

Dude, your getting fuckng annoying man, I don't wanna be mean, but you don't have to put a little KA-T comment in every single thread!!!

LOL it is in my sig and I'm gonna keep it there like it or not. I do check out both forums so I am not pushing people over to ka-t.org. I am simply enlightening

Good, it's in your sig, then you don't have to include it in your posts.

Well who knows who checks out the sigs anyway because people still talk about SRs when I pop up in forums.

i got the car for $400, some times i like it, some times i dont, i just want it fixed, i just got hit in the back, some laddy smashed my bumber, and my trunk is all messed up, i just want to fix the idleing problem, i went on 240sx.org, and read what the said, and i also tried wiggling the MAFS connection, but nothing happend, i was going to take my aiv out and clean it, but im afraid to take it apart, and not know how to put it back!!

Do you have any car buddies you can get to help you. I hate bringing my car to the shop. I rather do it myself. And take it apart. Don't be afraid. I would put each set of screws in different piles.

Then just try spraying some carb cleaner in the hose thats supposed to run to your airbox.

OK, i think i found were the problems is, i think.
almost every timei open the gas tank cap, to fill in gas, the tank relerase or sucs air, what i mean by that, when i open the cap, i feel and hear a release of air or mabye its pulling in air, im not sure.


usualy when i start my car, it would want to stop, but yesterday, my gas was almost on empty, it was on the first dot right befor the E, my car didnt idle too low, or go up, it ran fine from the min i turned it on, i drove about 12 miles, it was fine, i stoped by a gas station, open the cap for the gas tank, and their was that release or suction of gas, filled up like 6 gallons of unleaded gas. as soon as im making a left out of the gas station, my car started acting up, my idle was at 480 - 500 rpms, and it wanted to stop!!!

my car does that too, the gas vacuum thing, i think that's common. however, mine doesn't have your problems

so that might not be the problem, but worth checking out

That isn't a problem at all. Don't worry about that. A lot of cars from the 90's and up started doing that. It is common and its just because no air goes in the tank and the fuel pump draws out gas which makes it a little bit harder to unscrew the cap.

will, after i fill up gas in my car, it acts up and would want to stop, but if im low on gas my car runs fine
could my fuel pump be going bad?

Dude, there's suction because there pressure build-up in the tank to keep fuel pressure up, every single car does that. If you didn't have that, fuel could barely make it to the injectors.

if i have a 1/2 a tank of gas, my car runs fine, but if i have any more than 1/2, it would idle at 480 - 500 rpms, and on every stop sign, it would want to stop, "the lights kinda dim out"

i was just trying to clean the AIV, and 3 of the 4 screws broke?

what i do

my aiv is so filthy, do i need it back in

well i would find out the exact screws that broke and replace them asap, then if you cant clean the aiv or looks damaged just buy a new one or do you have the aiv plug?

k, i took my aiv out, " mabye i shouldnt have done that"
anyways, AIV it out, its all black on the inside, also the pipe that runs from the down pipe to the aiv is filled with black crap, is that normal?
and do i need an aiv?
i failed e-check, i had 4.8 CO, and the limit was 1.2
??????
HELP

Replace the screws at your local hardware store. It sounds like you are running kinda rich. Usually black all over is carbon from either too much fuel or not burning all of the fuel. Pull your plugs and check them. If they are black, then you should clean them or replace them. Try testing the coil as well. Pull the coil wire from the distributor and place the end of it close to a ground point on the car. I use the strut bolts. Try starting the car and watch for the connector to arc to the ground. It should arc pretty well and in a sequential pattern. Once every .15 seconds or so. If it seems weak or arcs erradically, replace it. My coil went bad and I expirienced surging, stuttering and such. Make sure your timing is correct as well. That would also be a factor. 20BTDC for KADE and 15BTDC for KAE.

Here is my problems "Still"

1.) Car has stalled twice - i was trying to burn not "not nutral slams" - My frind came over, unpluged my Fuel Pump's Fues, he got it running, till next day it died right after i filled up with gas, i added some fuel injector cleaner in the gas tank, car still didnt work till next morning, it has not stalled since then.

2.) Car idles at 480 to 500 rpms when stoped at a light or a stop sign - most of the time it happens right after i fill it up with gas - I took the AIV out, the car still does the same thing. Right now the aiv is with my frind, he's cleaning it and replacing some screws i broke.

3.) I failed e-check, i got 4.8 CO the limit is like 1.2.

any1 know were i can find a manual for my car
its a 89 204sx "not a hatchback" auto - KA24E SOHC

k, remember how i said i got hit in the back "car accedent", will, i took the car to a body shop, and after 4 days, i cheked on it, they said it cant be fixed, the chassis is messed up "from the inside of the trunk, and its too rusted"

will my car and problems are gone, but what should i get next?

man...that just takes us one away form one hundred on the how many out there thread :(

Well thats a pretty sad story. Part the car out and get something else. Getting anything from the accident?

not yet, but, what kinda car should i get next?

a 240

when i dropped my ka24de in at 3000 RPM and the problem was the aac(auxilary air control you might want to check that first and then check the aiv because if water gets in the manifold it sits in the aiv and rusts the spring out. if that is bad i wish you luck on getting the part i was only able to find it at a junk yard and from Nissan.

Could the AIV be called the EGR, they seems to have the same description???

at Auto Zone, the EGR is the AIV?

any1 got a car for sale?

no this is clean air intake only its located under the intake manifold(its a b**ch to get too.
EGR is located at the back of the motor

EGR=Exhaust Gas Recirculation. Its the metal pipe running from the back of your exhaust manifold to the back of your intake.
IAAV=Idle Air Adjustment Valve. Bigger hose connected to your plastic intake. Right in front of the throttle body.
AIV=IDK. It is supposed to take unburnt fuel out of the exhaust manifold and recirulate it back into the engine. Located on the drivers side of the engine bay between the exhaust manifold and the air filter box. Its the little black box with the metal assembly below it. That little assembly is the actual valve.

k, i need some help!!

i can either choose to total the car and get 2000 from the insurance company, or i can pay them 125, and do this "savage title" thing, and then get the 2000
what my qestion is, what is a savage title, and does any1 want the car, ill sell it, cheap..

Think about it man. Sell it for cheap or get $2k for it?

im keeping it with the 2k, i just found some nice head light conversion, the look soo good

here they are:

Get your car fixed before you get those headlights.

k, im selling it, any 1 intersted , please e-mail me for pics and info


hanster24@yahoo.com

k, my car has toooo much carbon oxide, any1 know anything about that? i took my car to e-check and i failed, due to too much carbon oxide!!!, but they said that i am doing good on the part that most people fail.
remember how i had the idle problems, will, it seems if i have my CD Player off, the car doesnt idle too low or high, it just works!!!!

carbon monoxide or dioxide? there's no such thing as carbon oxide.. and that may mean you're running lean.. i'm no expert at emissions but that would make sense to me
