99 GT Coupe shuts off while driving....HELP!

**grandprix17** · 07-18-2010

Hey guys,

My GT coupe for some reason keeps wanting to shut off when I'm driving and it is not good. It has happened to me numerous times. I have taken it to Pontiac and since the car doesn't have a check engine light on, they can't find anything and says it's fine even after testing and keeping it for a couple of days. What should I do? I'm thinking of selling it cause I don't like driving it knowing that ant any moment it will shut off

Crank Position Sensor can make it do that. I would try replaceing it, also does the rpm gauge ever drop to zero while driving, if it does the CPS needs to be replaced.

its ur computer or ignition switch or crank senser like FFDP said. my moms regal did the same thing turned out to be ignition switch but it got so bad we couldnt hardly drive it or start it luckily we only lived 2 blocks away from the dealership so we just drove it over to them and had them look at it.
