I have an '89 SC 5 speed. When warm, it will fight to idle or stall when I come to a stop. The warmer it gets, the more prone it is to stalling. It also seems more prone to stalling when I stop hard. It never stalls when it is cold.
The engine is recently rebuilt with lots of performance parts, but it did the exact same thing when it was bone stock.
I have tried adjusting the idle speed set screw and it does not seem to make a difference.
I have heard that there is a procedure to teach the ECM to idle. Is that true?
Is there a procedure to test the IAC valve or the BMAP sensor?
Any other ideas?
