Re: HOLY CRAP!!!!!! My ignition coil is glowing blue!!!
The blue glow is called a corona. Its caused by the loss of electrons thru the insulation. If I recall, it can be caused by carbon tracking in the cap. If you take the cap off and rotor and examine them closely you may see black tracks in them. You might have a cracked cap too.
I would suggest installing a new cap and rotor, and testing the wires for resistance, and installing everything with silicone dielectric grease around the nipples for the cap, and the spark plugs, and the one wire leading into the coil. I personally would change spark plugs too. AC Delco, cheap and OEM.
