I've got a brain buster of a problem w/my zx3

My Focus has no fan without the A/C on. Plus has no midrange horsepower. High rpms (exactlu 3200rpm every gear)has great horse power. Codes read pcm and 2 oxygen sensors. oxygen sensors have been removed for the last 85,000 miles. The car has 110,000 miles on it. Idles ok. sputters from idle to 3200 rpm. Just replaced MAF. Had chip in car...took out to get codes. Cannot find thermostat control switch for fans anywhere on the engine. If I remember correctly I have always had a pcm code from running a chip. As expected Diablosport will not respond with anything but defensive answers toward their chip.

PLEASE HELP ME!

Mike

wait, you're running with no o2 censors?

Yeah Josh no 02 sensors. I haven't had those for about the last 85,000 miles. Diablosport bypasses them. I really don't think car computers are as smart as people think.

I'm chasing the thermo switch now...I'm wondering if I'm too fat because the car thinks it hasn't warmed up.

the chip itself wont bypass o2 censors, you need to get o2 eliminators


and your cars running like crapo and you have CEL because you have no o2 censors in

You have to run o2 sensors with an OBD2 car, as that's how the ECU finds the correct Air/Fuel ratio. You'll be lucky if no permanent damage has been done from beyond mile air/fuel ratio swings.

Diesel Tuner,

Dude.......I'm telling you. IT RUNS WITH OUT THEM. They haven't even been under the bonnet in forever. NO BS!

Shoot...I'm talking to kids. Neither one of you is over twenty. You two thick heads need to get with the program. By the way nice paint job on that mustang....did it come in a can? Call Ford racing up here in Detroit where people actually build these cars. In fact I'll get you in touch with some of Ford executive engineer friends of mine. But apparently you two knuckle heads don't listen. You must be the smartest people on earth because you read a spec sheet. Bite me. Take your expertise and shove it!
Mike

so you tell me how the car measures A/F ratio with no o2 censors?

calling us stupid and your the dumbass who runs your focus with no o2 censors and then wonders why it dont run right..

take your questions and shove it! :)

A car's ECU (OBDII specifically), or PCM if you will, measures Air/Fuel Ratios through use of the first oxygen sensor, and the second makes sure your cats are doing their job for emissions. An aftermarket piggyback computer or chip will not bypass these sensors, as they are especially important to keeping your motor running correctly and safely. I would seriously recommend reinstalling the oxygen sensors. If you are running a high flow cat, or even catless, get a spacer or a wire in resistor for the second oxygen sensor so that you don't get a CEL due to emissions. These usually run from $15-30, so there's no excuse here. This will be a start to finding out what exactly is wrong with your car.

I don't think that the computer is the ignorant one here. Your computer is throwing codes for the PCM (due to your piggyback, chip, whatever) and OXYGEN SENSORS. Quit denying the issue at hand and telling me that I'm thick headed and need to "get with the program", then telling me to shove it. I was simply trying to help you and offer some friggin advice to try to help you. You're a moron if you think that your car can safely run, maintaining stoich without going rich or lean, without being able to have an input for it's air/fuel ratio.

Furthermore, I find it funny that you don't list your age in your profile. Just because I'm 20 doesn't mean I don't know shit about cars, but at the same time, it doesn't mean that I don't have any knowledge of cars. That doesn't mean I have all the knowledge in the world on them either.

This knowledge is not from a spec sheet; I'm a Subaru guy and could care less about one of ford's spec sheets. This is common, universal knowledge. The symptoms of now low end power and sputtering is pretty common for an O2 sensor problem. Furthermore, your car is telling you that it needs the O2 sensors by throwing the codes. It's pretty plain to see, just from basic knowledge.

Your infinite wisdom has once again proceeded you. The O2 sensors are not the problem you thick headed kid. Get with the program you liberal snot. Support your neighbor. Uphold the constitution. And respect your elders.

Your infinite wisdom has once again proceeded you. The O2 sensors are not the problem you thick headed kid. Get with the program you liberal snot. Support your neighbor. Uphold the constitution. And respect your elders.yes they are, my car ran just like yours with a bad o2 censors.

if the o2 censors weren't the problem why would the CEL be throwing o2 censors codes?

You call us thick headed when your the fucking retard who can't understand why his car runs like shit- has a CEL that says o2 censros and then argues with somebody who knows (me, contour zetec = focus zetec) and says its not the o2 censros when the FUCKING ECU IS TELLING YOU IT IS!

god, i'm fucking finished. you must be the stupidest person in your state

Your infinite wisdom has once again proceeded you. The O2 sensors are not the problem you thick headed kid. Get with the program you liberal snot. Support your neighbor. Uphold the constitution. And respect your elders.

What the hell was that all about?! Resorting to name calling is bringing you down to a very low level, and killing any credibility you may have on the boards. How do you know that the O2 sensors are not the problem? The more you make a fool of yourself by making baseless accusations about age, the less likely it is that people will help you.

Your infinite wisdom has once again proceeded you. The O2 sensors are not the problem you thick headed kid. Get with the program you liberal snot. Support your neighbor. Uphold the constitution. And respect your elders.
I just stated that this is common knowledge. I don't have infinate wisdom and I'm telling you from personal experience. When your car's computer is recieveing a bad signal, or none at all in this case, from your oxygen sensors, it cannot sense it's air/fuel ratio. To protect itself, it will dump large amounts of fuel, causing not only a crappy idle and rich mixture, but bad gas mileage and lack of power. Rich is a performance killer. Reinstall the oxygen sensors and reset your car's computer (IE: unhook the battery, pump the brakes, and allow it to sit 1hr before hooking the battery back up...this is how it works on my car), and I can almost garentee you that you will no only see more power out of your car, but your idle will get better and your gas mileage will increase.

Again, I'm not a know-it-all. I'm just trying to help you, but you won't listen and just try to argue. Not only am I telling you that it's a good possibility that the oxygen sensors, or lack there of, are your problem, but your car is telling you the same thing.

Lastly, for this post at least because I know you're going to argue some more, you're a very poor judge of character. I'm not a liberal and feel insulted being called such. I'm actually a conservative republican and stand so very strongly. I don't agree with some things that have been done in the current administration, but that's life. No one's perfect: Not Clinton, not Bush. I don't see what my political views have to do with you having car trouble though.

Edit: And as far as your, "Support your neighbor. Uphold the constitution. And respect your elders," comment...

I do support my neighbors. I'm a Volunteer Firefighter/EMT for Loudendale Volunteer Fire Department, where I'm typing this right now. I spend countless hours training in disaster drills and in classes to serve my neighbors and protect their lives and property, while risking my own. This is at absolutely no pay. That's right. I don't get paid to protect this community or to risk my ass doing so. Now do you support your neighbors in half the capacity that I do??

As far as upholding the constitution, I do my best to do so and I believe strongly in the rules and rights that our previous leaders have laid out in it. I plan on testing for both South Charleston and Charleston Police Departments in the upcoming 6 months so that not only can I make a faithful attempt to uphold the law, but to uphold our constitution. What are you? A desk jockey? Uphold your Constitution.

And respect your elders. Let me advise you of something you obviously aren't aware of. Respect is a two way road. You earn respect, and will only do so by giving it. Speaking to someone as you have done will net you not a damn bit of respect from anyone. Respect that.

Okay young einsteins....it was the thermo switch and the car was choking itself because it didn't know it heated up. To others my Focus gets well over stock horsepower and gas mileage...in fact it gets 32 mpg in Detroit and near 40 going up north. For those of you who don't believe it would run, well son maybe I'm just smarter than you. You should perhaps research your roots and tune some carburators...so you know how it werks b4 U b-CUM N xPrt. Disd U.

I don't think I left anything out. The problem with thick headed people it they never glisten.

Whatever you say man. We all know who's thickheaded. You're dumb ass isn't worth my arguement.

You guys are cracking me up. Especially mr stringcheese here. Telling people to go tune a carb shows your age. Once again, we have a fine example of someone from the days when you tuned the carb, not the computer who is passing judgement upon this generation of gearheads. It's people like you who pull onto the road in a late 70s model muscle car, thinking they own the road, only to have their doors blown off by someone in their 20s running a turbo on a 4banger making more horsepower with half the cylinders. Congrats, you found out that your focus's problem was the thermo switch. But look at it from everyone elses viewpoint (if your head isnt too far up your own ass), if you tell them you have no O2 sensors, and your having problems with air/fuel ratio and your ECU is throwing codes at you, the first thing a mechanic is going to check is to see if the lack of O2 sensors is the problem, just like everyone did. But no, you resorted to childish name calling and insults, which gets you no where in this forum. As for the research your roots comment, many of us do know our roots. Maybe you should take your own advice and research your future, since its the cars of today that are consistantly ripping the cars of yesterday a new ass on the street and the track.

Also, in case you didnt notice because you didnt have your bifocals on, the mustang in sk8ter_in_ny's pic is a toy car. Looks about 1/24 scale. And you're calling us the dumb asses. :lol:

TWIZZLE DOG....RE-READ THE POSTS. How does a car that needs O2 sensors to run do it with out them for 85,000 miles?
Also wasn't there a fuel crisis in the seventies that severly slowed the muscle cars of the 60's.
Besides these are street automobiles. There's not a car on a track under 700 horses. Let alone 500. Most old muscle cars have well over 1200 before they remove thier lights to hit the drag tracks.
Just remember Detroit had the first paved road for automobiles in the ever in the whole world.

:eek7: wtf does all that have to do with you being an asshat?? Most muscle cars have well over 1200 before they ever hit the track?? Where did you come up with those numbers?? 1200HP would torque the living crap out of most unibodies without extensive reinforcing. No one I know here has half that HP in their muscle cars, but yet almost every single one of them is at the drag strip every thursday night. I believe 1200HP is more of a top fuel number, correct??

Also, your car may run without o2 sensors, but unless you're chip is ghosting a signal for the o2 sensors, which can be very bad in the event of a mishap, your focus will never run to it's fullest capabilities.

And what does Detroit having the first paved roads for automobiles have to do with anything? Just because you're from the Detroit doesn't mean you're all of the sudden an automotive know-it-all. Maybe you need to study up on the present and future, just as twizzle said. Carborators are obsolete, old man. Get with the times.

Once again, we were only trying to help you out and you started with the stupid crap of, "well I'm older, I'm from detroit, I have friends that work for ford, you're not as old as me, and you're a liberal." Please...spare us all the childish BS. You're worse than the ricers... :owned:

Twizzle dog? wtf kind of lame ass attempt at an insult is that? Apparently you don't know much about todays cars at all or keep up with current trends in drag racing. I can guarantee you that you put a Charger making 700 horses up against a WRX making 700 horses to not just 2 wheels but all 4, guess who is coming out the winner? It sure as hell isn't the Charger. And it doesn't have to be a WRX, it can be a Supra, a Skyline, or any other sport compact. That Charger is getting its ass handed to him. But this is beside the point. The point is you're being a real prick when everyone here was merely trying to help out a fellow Focus owner. Once you started being an ass to everyone who was trying to help, it didn't matter what your cars problem was. From then on, the problem was you being a real ass to people who were trying to help. Maybe you shouldn't fuck around with a car that you don't understand. Once again, research your present and future. The past is exactly that, the past. Meaning you can't always take what you know about cars from the past and apply it to todays cars. Its because of this you fucked your Focus up. :newbie:

Assuming things and jumping to conclusions are also characteristics of being dense or obtuse. Hey world I'd like to know, have I made my point?

what point? you have no point. All you did was be an asshat towards people who were trying to help you. What's the point??

apparently his point is that you can runa car without o2 censors,

sure, you can.. but it's very harmfull to the motor, he's too thick headed to realize it.

and twizzle, 1/18th scale :smokin:

Ha ha, I was close to scale :biggrin:

Whoops....Iguess he can't even afford a real STANG!hahaha....L.O.L!!!

Whoops....Iguess he can't even afford a real STANG!hahaha....L.O.L!!!I'm sorry I don't have $35,000.00 laying around..dickhead

LOL what sk8ter said (HEHE)...dickhead hahaha

Whoops....Iguess he can't even afford a real STANG!hahaha....L.O.L!!!
must be why you're driving a focus, eh?

and don't start sayin you own one until you can get me a picture of one with proof that you own it in the picture.

Probably no credit either!!! hahahaha (still laughing!)

I wouldn't buy a kid car I just use my Focus for work to keep from getting upside down on cars. I put too many miles on to drive anything else for work.

ok yea right i had un hooked my o2 sensors on my contour and it ran like shit and only got like 14mpg so why dont you hook up your o2 sensors just to see what happens and you act like a little bug that needs to be smashed ha ha

just a thought but I have looked at aftermarkets ecu's for the Zetec and they do have an o2 disable feature, BUT it is for the second sensor, for people who run a race header (aka no cat) and it just simply keeps the light on the dash off, the first o2 sensor is still needed as people said to keep the air fuel mix right, maybe your right and your chip is not requiring it because it is ghosting a signal but thats not ideal because it dosent know EXACTILY what ratio to run knowing approx what ratio is good, but exact is better, remember, the sensor is there for a reason, and plus whats the harm in putting it in just to see what happens, there is nothing wrong with being wrong once and awhile, everyone has been, how do you think we learn all that we have? whats the worst that could happen anyway? ether nothing will happen or your car will have more power, (ps use a new one, that way you are gaurenteed that it hasent been fouled)
