I think I should add a little more information to my inquiry.
The car is a Saturn SC1 year 2000. It has about 84,000 miles.
I recently went to a mechanic when I noticed the problem and he diagnosed it as a bad engine coil. But upon further investigation with a friend of the family, I learned one of the key indications of a bad engine coil is a lack of acceleration or trouble excellerating. This is not the case with my car. Granted it has a small engine so it's not speedy to begin with. But I have not noticed any change in excelleration. I'm more than a little hesitant to pay big money to replace a part that doesn't need replacing. So I'd like to have a clear answer as to whay could be causing the problem.
If this helps. The racing idle occurs when the car is both warm and cold. If I turn off the car when it is racing. And restart. The engine corrects itself and idles around 1,000 rpms as usual.( The fast idle is anywhere from 2 to 3 thousand rpms.) It is a manual transmission car and I have learned how to prevent the fast idle. If I slow the car to under 15 hundred rpms before depressing the clutch and coming to a stop. 9 times out of 10. It won't idle fast.
