I've looked all over online to find a good answer to why my new plug wires would be arcing and can't find one.
A quick rundown on my car: 91 LX 5.0l. I just put a new Blueprint engine in last summer. It has almost 500 miles. I have replaced every sensor and solenoid I can find. It has a new MSD distributor. It misses out until it warms up then runs great. Last week I opened the hood in the dark and noticed there was arcing on nearly every plug wire. They were new last year but it was an opportunity to upgrade, so I put on a new set of custom length MSD wires. I opened the hood in the dark this week and was very surprised to see the exact same thing. Every wire was arcing to some extent. The most interesting part is that when I touch the coil wire and run my fingers along it, the light arcing follows. Btw, I did put a new stock coil in last year too and it has new plugs gasped at .45. I did repaint the engine bay when the engine was out. Is it possible the coil isn't grounded good enough because of the paint?
Thanks,
Mike
