Check the IAC (idle air control) valve yet? Pulled the codes yet?


Can you be a little more specific with what it's doing???

the idle drops very quick right until it reaches full operating temp after pushing in the clutch.

after its warmed up fully the idle hangs just like the average hanging idle thread.

hangs at 1k until the car is fully stopped for maybe a second.

Mine does the same thing with the ac on. Hangs at 1k until i come to a complete stop, then drops to normal idle rpm. I've always assumed that's normal.
