99 pontiac grand prix won't run/stalls after a few minutes and then hard to get to start back
The car stalled out one day at a red light. It started back and kept going. It stalled out again and had a hard time starting back. Finally, driving down the road at 55mp it started jumping and cut right out. Would not start back for a while. After sitting for a bit, started back and would not idle and cut right back out. We had a 0102 code that said MAF sensor. Replaced the sensor and started up and cut back out after 4 miles. Tested the cam sensor, and it was fine. Replaced the Crankshaft sensor and it started up, idled for about 4 minutes and shut off. Gave us the 0102 code again now. When you press on gas pedal, it revs up and down and then cuts off. Any ideas?
