Grand Prix stalls out when accelerating
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.
I got one on order. I will try and hopefully this works. I'm running out of ideas. Anyone else have anything?
I'm having the same problem. Just wondering if the new MAF sensor fixed the problem.
