the first time it happened was after a long trip. at the light it almost seemed to rumble and almost stalled out. then when I got it home it was hard to restart. now it happens every week or so , I feel it start to stall out (that's the best description) and I step on the gas and it stops.It has 100,000 m and never did this before .

Answer #1Superbob November 27, 2010, 14:26Master
it's possible that the Idle Air Control (IAC) is fouled with carbon or has gotten stuck and failed. I'd think there'd be a check engine light on if the IAC is not functioning right, but maybe not. If you know how, you could remove the IAC and clean out the passages, or you might someone do it for you.
Also possible the IAC has failed and needs to be replaced.
That's not all that could be wrong but it's the first thing that comes to mind.
The second thing is that the Airflow Meter is malfunctioning, but the check engine light should be on for that too. A good technician could check it all out for you.
