ever since i changed my oil the other day the car has idled funny!!!!!!!!! sumtimes it stays reved up between 1k & 2k, other times it lopes really fast, or it just lopes slow. the engine light stays on because of my intake manifold and test pipe. i reset the ecu and no changes, can anyone think of anything else 2 check. i didnt knock off and hoses or plugs and plus i already checked that stuff.

 

Check your TPS
Check for Vac leakes
Also check your Intake manifold gasket and you spark plug grommets

 

Yeah, check all the stuff he said. Also check IAC valve and alll the collant lines to the intake manifold.

 

I have the same problem.....i had it before then cleaned out my tb area and it worked fine.....but just a few days ago it started doing it again.
