Fellow Bricksters:
This problem just started. My 83 GL's idle surges or hunts (not sure which is the correct term) from 750 (spec idle) to around 1k RPM. Engine (B23F) runs great! I've cleaned the IAC just recently, the TB was cleaned and adjusted about a couple of months ago and I searched for, but didn't find any vacuum leak. I also switched the ECU with a known good spare. Could it be a bad AMM? Fuel system problem, maybe? BTW, I have not check any of the electrical signals to all the components I have mentioned (IAC, AMM, TPS). Not too confident on my elctrical (checking skills). Any suggestion will be appreciated.
