Grand Prix stalls out when accelerating

5

Asked by Jan 13, 2014 at 05:46 PM about the 2004 Pontiac Grand Prix GT1

Question type: Maintenance & Repair

My 2004 Pontiac Grand Prix will stall out if I press on the accelerator. I have ran codes and they come back MAP and MAF sensors are bad. So I replaced the MAP and cleaned the MAF and reset the codes. And it still stalls. I then replaced the fuel filter, cleaned EGR valve, checked for vacuum leaks, cleaned distributor caps and wires. I still have not located the problem. The vehicle will run but if I push too far on the accelerator it will stall out and I can start it back up. Any ideas?

Cleaning the MAF usually won't work Replace it and see what it does. When you cleared the codes it will take at least 2 drive cycles to reset the check engine light.
