2001 pontiac grand prix 3800 series motor.
while driving, the motor would rev and idle high, then misfire and die.
then the car would start back up and run fine..
over time the problem got worse, now the car will not start at all.
we've replaced EGR valve

Hi I'm having the exact same problem.. I have replaced the MAF, the crank sensor, the MAP sensor everything in my 2001 Grand Prix 3800 has been replaced! I was wondering if you had fixed yours? And I also own another 2000 Grand Prix and took the brand new MAF out of that and it still was still dying. I had to clear the codes to restart. Please help
I had a 01 grand prix GT, with very similar problem. I processed by way of eliminating the fuel pump, ignition module, catalytic convertor to determine it was 2 bad o2 sensors that didn't register on diagnostics. Hope this might be helpful, and good luck.
