1996 Bonneville Pontiac (Not supercharged) When slowing down to stop the engine sometimes kills. Sometimes outright and other times the rpms revs up and down a few times and then kills. Along with this the car sometimes lurches slightly when slowing down to stop. It always starts back up fine.. I don't know if this is part of the same problem, but when traveling at a steady highway speed the car seems to lose power for just one second then resumes speed. It does this between one and 6 times in 15 miles. What can cause these problems?
Ignition modules can cause problems like this also airflow meters and faulty fuel pumps
