This car is computer controlled, and assuming it has the Chevy 305 it is also fuel injected. There is probably a problem in the computer controls causing it not to idle. Do not attempt to adjust idle, as it will not fix it, and may cause other issues when the innitial problem is diagnosed and repaired.
vacuum leak. my 95 Monte Carlo did it. once in a while it would race to 2500 rpm then settle down like normal. not easy to find , but a cheap fix.
I have a stering colum that is loose and feels like it will fall in my lap.What is going on and how do I fix it?

I have the same problem with my 03. I havent figured out the check engine light but take it to a dealer and they will fix the idle problem. they know about it and if you take it to them they'll fix it for free. it has something to do with the computer needing to be cleaned out.
