Wierd problem

by **pvu** » Sat Feb 11, 2006 9:41 pm

This has happened to me many times. I start my car up and it seems the engine started, but it wont stay on. The rpm barely reaches 1k and the engine slowly shut off while making a nasty sound and the check engine light would come on. Then I restart the engine and everything's fine and no more cel. This doesn't happen everytime but once in awhile. My car is a 99 and has over 100k. What could the problem be?

clogged fuel filter?
clogged catalytic converter?
fouling spark plugs?
ignition ok?

just a few questions I would ask myself in your situation...

Sounds like a bad Idle Air Controller (IAC). If you rev the engine will it stay on?

Never tried reving the engine. I will try next time and see what's up.

HAD The same EXACT problem......if you try revving the engince does it seem like only a couple cylinders fired.....its a freaky problem....mine would sometimnes take like 5-10 try to get the damn thing to start........but when i cleaned the throttle body it seemed to stop.....it hasnt done it in at least 3 months

did you guys find out what the problem is? throttle body needs cleaning?

It happened to me for the first time today, cold idle at 200 w/ rough trembling for like 5-10 seconds and dies. After a few times turning restarting and going nowhere, i revved the engine at 2000 and kept my foot there for a couple minutes, then everyting goes back to normal, as if nothing happened.

I got an I4 w/ new batteries, had oil changed and added K&N drop in last week, so maybe the ecu is adjusting to the changed air flow and the new oil?

^ nope... car stays on to adjust settings.

sounds like what yanks said.

Mines doesnt do it as much anymore... But it does drop the RPM TOOOO low when I turn the A/C on.. Could that be a sign? Because I cant up the RPM throttle line anymore. I already max it out.

clean the throttle body and seafoam it. It should clear up this problem.
