1999 Pontiac Grand Am 2.4L SFI DOHC 4cyl
when I come to a complete stop the rpms drop for a split second and then the engine starts to shack/run ruff. And when I shut the car off it shut off ruff.
when I am driving between the speeds of 20 to 40mph my RPMs get jumpy only if I am not pushing the gas peddle
P0507 Idle Control System RPM Higher Than Expected
