Idle problem

[roadburner]

Hi Guys,
my SE starts normally when cold.But after warmed up the engine revs between 500rpm and 1050rpm at idle.Sometimes the engine stops.
What kind of problem is it.

Thx!

P.S.:I got no fault codes on the Ecm and resetting doesnt help.

Sounds like it could be your ECU trying to correct for a faulty EGO (exhaust gas oxygen) sensor. It could also be a faulty IAC (idle air control motor) but this would be more unlikley as the IAC is not supposed to be engauged at standard running temp.

I would suggest getting your EGO sensor checked first.
