99 Pontiac Grand Prix Shutting Off Randomly

Asked by Jan 19, 2016 at 11:52 AM about the 1999 Pontiac Grand Prix 2 Dr GT Coupe

Question type: Maintenance & Repair

I have a few issues that have all started happening within the last few weeks:

1: My car will randomly accelerate on it's own. It's random. It may do it at a stop light or it may do it at a higher speed.

2: My car will randomly turn itself off. It will die in the middle of driving it. It does this particularly at stop lights, or slower times. Lights will dim randomly at times and the car will accelerate at these times, almost as if it accelerates due to less power.

3: My low oil light came on. I changed the oil sensor and it is still coming on. It does this randomly.

4: When I turn I hear a random ticking noise. I passed inspection and got an alignment with no issues. This could be completely unrelated.

Any ideas? I have so many symptoms I'm thinking there's got to be something specific surely.

Have the codes read. Even though its an older car there is data stored on the car's computer that may tell you what is going on.

MAP Sensor and PVC Valve.
