Engine Performance problem
1995 Pontiac Grand Am 4 cyl Front Wheel Drive Automatic 140000 miles
car will idle fine but every 20 sec. Or so the engine idle will stumble, While driving ( highway speed its most notesable ) the engine will surge not under accelleration but when speed levels out or slightly backing off accellator. Replaced fuel filter, no change. This has been a problem for months steadly getting worse.
have the same problem?
