Author Topic: Ruff Idle Keeps dieing (Read 2723 times)

Ok i did all the vacuum lines under the intake. All my coolant hoses and also the intake gasket, O2 sensor, Spark plug wires, spark plugs. It is still running really ruff and acts like it doesn't want to stay running. When i rev the car up to around 2 grand the studder and dieing seems to fade. My car really doesn't like to run when its taking off, it sounds like its misfiring either in the head or in the engine. It tries to die when I'm starting out or in the HIGH rpms! It has 0 power and slows down when i hit around 75% throttle.

I checked my compression on all 4 cylinders and i have 200+ on each! I also tested the resistance on my AFM and it seems to working fine! I did notice it has a funky adapter on it, which it doesn't work without.

Yea mine too. I have already done a COP conversion, it seemed to help but still has the problem. I have checked the Crank and cam sensors plus connectors and they seem fine. I will be replacing the injectors soon with the four pintle style, hopefully I will have this beat by summer.

If you get this resolved please post what you did to fix it.

have you cleaned your ICV?

Was the car running ok before you performed your fixes?

It was runnin like shit before all the new parts. it got better with each part but it still is runnin like crap and wont idle. I've been thinkin about injectors and ICV. I didnt know you can clean it! What do you use to clean it? do i need to be careful not to damage anything?

Lile KenCopperwheat mentioned above - check your throttle position sensor. Maybe even your throttle body has shit itself - but I would check the tps first.

Also have you tried checking for fault codes?

I took it down to the dealership and it gave an AFM code and O2 code. I have brand new o2 and the AFM seems to be working fine we checked the resistance and it was fine. My buddy at the dealer told me i should pull the intake and do the hoses under the intake. My throttle body is clean but it must be the sensor. Perhaps i still have a vacuum leak some how.. All new vaccuum hoses the car runs better but still check engine when steady on the gas cruising.... dont understand what code that one is but its gotta have to do with the ICV
