B18A1 Problems

[Tony]

Ami and Jer already know about the problems I have been having. Seems when I fix one thing, another problem surfaces.

When I first dropped the motor in, I got Code 14(IACV), and for some reason the firing order was off. Drove the thing for a week this way, I had too because its my only transportation. Got the firing order correct on it and then I start hearing a weird grinding noise coming from the transmission. Check the fluid and fill it up and still get the noise...pop the right axle out and back in and the noise goes away. Was driving the thing around today, was running good, then all of a sudden it acts like the timing jumped a tooth and I get code 16(Fuel Injector). Was talking to a friend and he asked if my speedo had been bouncy around 30 mph...right on the money. He mentioned replacing the distributor, which had been making some funny noises too. Called my dad to have him bring me a new distributor, and while waiting, I got the idea to reset the ECU. Reset it and it ran good for about a min, long enough to make it to a parking lot instead of the side of the road. Tried replacing the distributor to land in a worse boat than I was in to begin with, new dizzy doesn't want to fire. Ran out of time and had to be at work. Get off work and after talking to Jer, he said replace the IAT. Swapped that out and right off the bat I got Codes 4, 9, 10 on top of 14, and 16. Swap it back out and still got the codes(yes I reset it). I did get the car back to my house, made it most of the way fine, then after it got warmed up for a min it started acting up again.

Gonna go double check my MPFI wiring in the morning and hopefully get some ideas from you guys. I'm tired of working on the engine on this thing, I want to move on to other parts of it that need attention.

Oh yea, incase you got lost in all that. I put the original Distributor and IAT back on, haven't replace the IACV yet.

+2 to check the wiring, go over your solder joints, etc w/ a fine comb... make sure there's no oxidation, etc.

Did you use heat shrinkable tubing when you did the wire splices? If not, you pry should have, especially if you live in a "wet" area.

I seem to remember you saying something about maybe having two plugs in the wrong places b/c they're interchangeable... have you tried swapping them yet?

Those are about the only ideas I have for now, will post if I get something else later...

Other than that, work on it ONE code at a time... don't get overwhelmed by all those codes you're throwing, b/c if you do, you'll waste alot more time standing there sighing about how your car should be running, and you're losing this, or need to have it for that... and bitching is a waste of time

Well I swapped the harness over and found out that my connectors for the distributor wires were coming undone(cheap connectors). Managed to get rid of most of the codes, ofcourse just to get some new ones. The main ones I believe are just 3 and 6. The flashes are a little hard to interrupt. It starts with a big flash, goes into 3 quick ones, then 4(every once in awhile?) and then 6, ending with a long flash and then a long pause. So I'm pretty sure its code 3, 4, 6 and 10 now, but the car runs(most of the time, had it die once, just restarted it and its fine)

Really wish I would have spent more time on this thing while it was down, instead of throwing it together in a week finally.

[Christ]

the long flash could be 10... it could also just be "end of sequence"

I can't remember which ECU's used long for 10

glad you got that worked out, now just keep going at it, one code at a time, and you'll get them all... it's like pokemon man, you "gotta catch them all" rofl.. sorry, that was ghey

[FrodoGT]

b series use longs for 10

[Tony]

Yea, thats what I was thinking. And I must be crazy thinking code 4 is in there, must have been from before. Was late in my last post, its late now. Just got done with my final points race for the year, finished 4th overall, and that poor poor car is probably retired(might do one more race for the year).

Gonna end up replacing the IAT again on the B18, and checking the o2 sensor, see if its making it throw false codes. Just glad most of my racing for the year is over so I can spend more time on the hatch again.

also let the sequence run all the way through then start reading..i noticed that usually the first sequence is short by one ( how you were saying 3 maybe 4 sometimes) and i have to wait till it goes thru all the ones its throwing..

id say make a vid on youtube lol then we can all read your codes

[Tony]

Went and took a video to show everyone, then remembered I still had 1 more IAT laying around, so I replaced it and reset the ECU....no more codes. Now I just need to get new radiator hoses and cap and get a new heater core. Right now the upper hose builds up quite a bit of pressure and the cap isn't releasing any of it.

which engine harness are you using?

i was waiting for another phone call in which i was going to ask if you were sure the IAT you used was good

glad to hear no codes

when you going to come out and check out the new house...we've been here a year already!!! 5gJon lives with us, except he's 6gJon now

[Christ]

Glad to hear you got it fixed, even tho I was only here for "moral support" during your "dilemma" lol.. I tried :P

[Tony]

Well I just kind of used this thread as a release. I wish I wasn't hurried on everything like I was because I could have fixed it earlier.

BamBam: I was using a harness I made from my DX almost 4 yrs ago, and was confused on a couple plugs then, because it was really messed up. I now have another DX harness in there with my injector harness from the old harness.

Should actually be able to make it out there sometime next summer Ami. And tell Jer I'm sorry he had to put up with the idiot me .

[Tony]

And here we go again....just my damn luck here: Got a chair in the radiator last week, and Code 4 pokes its head back up, but goes away after cooling down and resetting....today I go to go to a friends house and just out of no where my right side quarter glass explodes on me(haven't figured that one out) shortly after, Code 4 makes its appearance once again, I thought I took care of it last time, apparently not once it warms up for awhile.

Think its the wiring or just the sensor is going out?

[Tony]

Woo Hoo! I've got a melted Coil and metal shavings!!! This could be the problem, gonna clean it up and see if I can mix and match some parts from an A6 dizzy and get it going again. Ill grab some pics of the coil too when I get a chance.
