I have an 89 Grand Am, It will start but seems to be running on 2 of the 4 cyclinders, idle is rough and if I run it for longer than 5 minutes the catalytic converter glows orange. I have changed the points, and the boots. It also smells like it is dumping way too much fuel. Any help will be appreciated. Thanks.
If this is one of the quad engines it is a coil pack. Don't which part. I've just bought the assembly at a auto salvage place.

These two hit the nail right on the head. :)
