1998 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 166000 miles
I have a 98 Pontiac GTP Supercharge 3.8 that shuts off after running anywhere from 30-60 minutes. The first time it happened I had let it gotten low on fuel and when I filled up, jumped on the freeway, it died while in motion. It started after about 15 minutes and I thought it was trash in the line. Since then it does the same thing every time, even if I'm parked and let it run. So, I changed the fuel pump, fuel filter, taken out and cleaned the MAF, TPS, Idle Sensor. Once I did this it ran a little longer while driving but eventually shut down. At first it would start after 15 min then, 45 min and now it has to cool all the way down before it will restart. Firestone put it on the diagnostic and found "No Codes". My friend used his hand held diagnostic and found "No Codes". Please help, I need a car to find work.
have the same problem?
