PONTIAC GRAND AM CHECK ENGINE LIGHT PROBLEM

1999 Pontiac Grand Am

1999 Pontiac Grand Am 6 cyl Front Wheel Drive

My 99 Grand Am is reving up and down and cutting off when stopped. Idoling very rough and idol sensor has already been replaced. What is this?

If Idle Air control valve has been changed, then check for vacuum leaks.

Are you getting a check engine light?
