My car turns over, idles but if i give it gas it drops rpms and if I give it enough it will die. like it getting choked by to much gas or to much air. cousin told me it could be the Oxygen sensor, any others.. Does anyone else have a possibility or had a similiar problem

 

Sounds like a vacumn leak ( a big one). If not that, the MA sensor could be wasted.

 

Yes, look for a vacuum leak.

 

there is no MAF if its the '90 listed under his username. 3.1s are all MAP based setups.

 

I suppose it could also be a severe out-of-correct-timing problem, too... one that gives a super-weak spark- but definately check for the vacuum leak first.

Let us know what you find!!!

 

could be a plugged cat or possible ignition control module. ive seen both do that

 

Plugged exhaust could cause it to do that. Take off o2 sensor and check for pressure in exhaust. If it's high, then it could be cat or muffler. To check which, you need to punch out exhaust right before the cat convertor.

Or vacuum leak...

 

culprit= bad injector

 

Musta been one HELL of a bad injector!

 

yeah, i dont think an injector would be quite that bad. a car can run on 5 cylinders, even if its rough. what hes describing probably wouldnt be caused by an injector.

 

That's him updating...apparently it WAS a bad injector.. Which was why I was surprised.

 

damn, i need to pay attention, lol. thats what happens when your manager quits and youre stuck managing a body shop..... w/ very little training, lol.

 

Congrats on your promotion.....or....something...

 

lol thanks. its been a nightmare, but the $$ makes it all worth it

back to topic, so it was a bad injector, hmmm. weve all learned something here.

 

it had to be more then that, a car can run on 5 cylinders. me qand my friends always pull each others injecotr clips off just to bust each others *****.

it'll run but smell like fuel and run rough.

 

I agree that its hard to believe the problems were from only a bad injector...but if thats all he replaced, and that fixed it....well....
