2002 4.3 sonoma 5 speed acts like has a vacuum leak around 3 grand and wants to stay idoled high for awhile. Have checked around the upper intake with carb cleaner to see if it was busted and nothing. Changed mass air flow and throttle position sensors also. Not sure what else to do?
have the same problem?
