After a recent trip to the track, my car is idling at 1100.

Micro switch is working, any other thought?

Thanks

Vacuum leak / loose hose?

Dirty ISV?

Checked both of those, Seems to idle fine when cold then 1100 when hot. Any other thoughts?

Mine was idling about the same, just over 1000 RPM, and my mechanic discovered the car was stuck in closed loop mode (fixed air/fuel ratio). Had to replace the DME to fix it. $800 for a used one but cured the problem.
