2006 Pontiac Grand Prix GXP Misses
I have a 2006 Pontiac Grand Prix GXP and when driving, the car the engine sometimes pauses for about 1 second causing lights to flicker and the check engine light goes on then off. After that the car appears to run normal until the next time it happens. Sometimes it doesn’t happen for 20 miles but other times, it will occur 5 miles apart. Computer does not store any error codes.
