I gotta see that. You sure you don't have a Deisel.

Did you just install the MSD coil? If so I would put the old one back one and see what happens. Also...How do you know the plugs are glowing, I can't see any of my plugs. Come to think of it, I can't touch half of them either.

Yes the coil is installed,and at night or in the dark (with the hood up) I can see them glowing.I'll try changing the coil But it didnt do it until after the new cam and wires were installed?

As long as there are not sparks coming out its ok. I think the correct term for the glowing is coronal sp? discharge
