I have a 1999 Pontiac GTP 3.8L supercharged. Codes are MAF and EVAP.
Engine bucks and farts and stalls. Replaced MAF still doing it. Will run for a few days after clearing codes and disconnecting the battery. Checked voltage on MAF and reads 2.62v. A month ago it was reving up and down and stall when it was first fired up...code P0102 & P0442! I had the fuel pump and resistor replaced last year.
Now it will die while driving in traffic! What happen to LIMP HOME MODE?
Any Idea's?
