2001 grand prix two ignition coils don't fire

I have 2 spark plugs not firing. one of the three ignition coils does not fire, the other two do, is the most likely culpret be the ignition control module? car has the 3.8 motor.

Ignition coil.


2 plugs are not firing? My gp had 1 plug not firing. I had a noticeable miss. Running on 4 cyls must really make motor run poor.

If you have a bad plug or wire on one cylinder not firing, it could cause the companion cylinder on the same coil not to fire.

Swap two of the coils. If the the non firing cylinders move with the coil, replace the coil. If the non firing cylinders remain the same, replace the module.
