Re: Revs stay high after gear change
Quite correct, it's not the same thing, your's was mostlikely a blockage that was cleared with the flush stage in the oil service.
This could either be the IAC as I said or ECU, I doubt the ECU is the cause as all guages would play up as well as all the other probs you should get when one of them goes haywire.
Get the garage to pull the IAC and give it a clean, I am convinced that this should solve it. I had a car in this morning with the same prob.
