It could be. Is there a check engine light on? I would check for a vaccum leak first.

No check engine light. When you say vaccuum leak, what exactly does that mean?
By the way, this morning it was fine so the high idling seems to be intermittant. It happens about every other day and when it is really hot outside.

A vacuum leak is when the engine is sucking air from a broken vacuum line or a broken gasket. You would hear a hissing noise under the hood. Sounds more like a temp sensor or a maf sensor since your talking about outside temp. You will need a scan tool to read those sensors to see what they are doing.

I am so sorry to keep bothering you, but now the flash engine light is flashing. I am going to take it to the mechaninc, do you still think this is a vacuum leak? Is this an expensive repair? Any other suggestions as to what it could be? The engine seems to be shimmying, the ride is much rougher now. I am considering trading the car off, so any advice/information you have is very helpful.
