2000 Pontiac Grand Am 4 cyl Front Wheel Drive Automatic
I have a 2000 pontiac grand am and when you start the car it begins to vibrate extremely hard and makes rapid clunking noises as if a hunk of metal was inside the engine. When I drive it, if you are soft on the gas pedal you can get the car to run close to normal, and once in a while it seems to drive and accelerate fine. I have replaced plugs, plug boots, coil packs, coil pack housing, fuel filter, and tested fuel pressure and still have same problem. Could injectors cause this problem or does it sound more serious? The engine seems to run solid otherwise.
have the same problem?
