Engine Performance problem
1999 Renault Megane Front Wheel Drive Manual 93000 miles

My car revs too high when idling. I have changed the idle air control valve but still continues to rev too high. It calms down a bit when the engine warms up but goes back up again when the car is started from being cold. Any ideas?

Check or replace the IAT (intake air temp) sensor ..
