940T Miss at idle

VTPOLAR · Post by **VTPOLAR** » 18 Feb 2010, 17:33

My 940T has a miss only at idle. Thought is was MAF, did not fix a thing. If MAF is disconnected, the miss cleans up. When cold, miss isn't there, within one minute it is present. Any ideas?

Have you checked for fault codes?

Attached is a list of other things that can cause erratic idle.

No I have not. The MIL has not been on. Could there be fault codes stored without MIL on? I appreciate your help! I will do a little more poking around.

Some fault codes can set without the MIL coming on. If I have a problem with my car I check for codes as a matter of course.
