A couple of years ago I bought a '97 Aero that had a high idle issue, it would be as high as 1300RPM once warmed up. I checked for the usual vacuum leaks, cleaned the AIC checked for proper operation etc. No luck!
I then noticed that once the engine was up to normal temp I could disconnect the cooling temp sensor while the engine was running and it would have no affect whatsoever on the idle. The cooling temp sensor checked ok. So I was running out of ideas, but was suspecting the ECU. I picked one up on ebay, replaced it and the idle issue was fixed.
The idle has been solid ever since for over a year.
At least on my Aero that solved the problem.
