You have to describe better the idling problem.
FOr a brief intro, the O2 sensor does not start working until ~30 seconds to 60 seconds after a cold startup. So it is probably unrelated to your problem.

I know its not the o2 senor. Just replaced it and nothering. LOL.


Ok..I will try this again. The car wont idle at all on its on when you start it up cold. If its warm it will idle but not cold. After a min or two of manual idle it will do it on its on but once ou rev the car up to about 4500 rpms and just let the tack drop the car just dies. Its like there is nothing to stop the tack from droping. Hope this helps. Thanks aaron

Wow man O2 ensor is like the last hting to do, cause it's so expensive.

Im thinking Oil Maybe? Are you leaking? maybe not getting oil pressure up or something. Did you set idle yourself? Check timing? Throttle position sensor? EGR? All the shitty little sensors that crap out on you?

Nah. I dont think the oil could have anything to do with it and I dont use any oil nor leaking. I havent checked the time. I thinking the cable. I the car kepts droping down to like 500 rpms and then I drive a while is raises back to 1000. Its weird. I am at the point of saving me money and going to the dealer but I will try other things. As for sensor, I dont know jack about them. Where are the others at besides the o2. It didnt do this til I put a CAI on so I think it maybe something to do with the air system. Thanks aaron

same thing here.. when i put my CAI on is when i got probs.. i have adjusted it multiple times and still occasionally have probs with .. warm starts=rev to 2g's and die.. cold starts=fine... sometimes it sounds like it having a problem getting goin in the morn.

Oh yeah! Mine did this too when I put a CAI. Adjust the Throttle position sensor.

Also clean the throttle body if you haven't. Hope that helps

I had the same problem on my Eclipse. It turned out the oil change place had pulled the temp sensor plug, and the ECU had no idea what the temp was. Check the 2 plugs above the oil filter on the intake manifold. You may have unpluged one of those when you changed the oil, or something. Also check the ECU codes. Just because you don't have a SES light, doesn't mean there are no codes.

hey ben, we gotta adjust my tps :D

my car's idle has been weird for a while, its still messed up
i guess its the tps because i did everything else
