Question about 1999 Pontiac Montana
Runs better with the mass air flow sensor disconnected. but free engine it won't rev up above 3800RPM
Scan for computer error codes and post them so I can see them. Most of the chain type auto parts stores will do a scan for free. Try cleaning the MAF, but note that the contacts on the MAF are very delicate. DON'T TOUCH THEM WITH ANYTHING!!! Use only "CRC" MAF cleaner and be sure to follow ALL instructions on the can.
