Just got back from what seems like a wasted 3 hours at the local Isuzu dealership. I've been having problems with high (and irratic) idle and the check engine light staying on. I've done darn near everything there is to do to correct the problem and now the Isuzu tech tells me my PCM (Powertrain Control Module) is overheating and needs to be replaced. I've never heard of the PCM, is this the same as the ECM? Would it effect idle if overheating? He quoted me a price of $183.00 for the part.

All help is greatly appreciated.
