Engine Mechanical problem
1999 Pontiac Bonneville 6 cyl Front Wheel Drive Automatic 142000 miles
Have been having a on again off again problem with the car dieing while I'm driving down the interstate or maybe even when im at an initial start up from a stop. The engine will die just like someone turned the ignition off. I can coast off to the side of the road and put it in neutral and it might start right back up or it may have to set and wait for anywhere from 5 minutes to an hour. This problem might happen on an every day basis or it might go two weeks before it happens again. Have had it in to the shop and of course they cant get to act up while there. They had a code saying the fuel pump was bad, so they replaced it but didnt fix the problem. The last couple of weeks it has started to act a little different before it dies. Now, it will start to hesitate and loose speed before it dies. If, I try to give it more gas I can keep it running but loose speed and it spits and sputters untill I let off the accelerator then it dies instantly. Have considered the crank sensor and the Mass airflow sensor as potential culprits, please help!
have the same problem?
