Well, it's not storing any codes, as the OBD-II scanner tells me life is good... I guess since it only happens at cold start and then goes away once water temps get toward normal operating temps, it clears itself??Since this issue goes away at normal operating temps, I am throwing out possiblities like fuel filter/regulator, tune items, and bad wires. It seems to be SOMETHING computer related at cold water temps that is telling the engine to run differently than it should.I did a little bit of interweb searching and found a couple articles on similar issues, and it seems the common link is the MAF sensor... There was talk of cleaning it with favorable results, but no description as to how that task is accomplished? I don't really feel like making a multi-hundred dollar mistake, so can anyone point me in the right direction on cleaning the MAF on a 5.3L GM engine?
