Question BAD Arch Good Ground?? Spit and Sputter?

I have a big arch coming from the trailing coil and i can figure out why.
The engine is grounded good with a after market big guage cable and from there to the frame rail.
Also the car sputters when its around 4500 to 6500 RPM's.
I think it may be a beacuse of the coil problem.

Any Idea's???

The arch is comeing from the terminals and going to the tower.

I know it makes no sence but the coil wires are brand new NGK Wires. With no cracks i checked that also

Mine does that too. Right where the leading coil sends its power into the Coil wire to dizzy, it sparks and makes my tach go weird. I have the same symptoms as you, so I covered the coil plug boot with electrical tape and covered up the positive and negative side of the coils. Not the prettiest thing, but it helped somewhat until I go get new plug wires.

Mine did this once and it was because the plug wire was not all the way seated in the coil. I also changed the cap and rotor and it helped but didnt solve the problem entirely.

Basically what fixed it other than the replacement of cap and rotor was I unplugged the coil to dizzy wire and spread open the part of the plug wire that attaches to the coil. Then I jammed it in there like the bitch it was lol. May also help to possibly take the connectors off the coil and clean them up. Could be a corrosion problem.

I've been pretty good. been hangin out keepin it real. You know how I roll lol. Actually, I start auto body classes on monday. Pretty excited/nervous. The first time I went to college (dropped out) I wasnt near as nervous. I am probably going to be the oldest guy in the class though (27). I do know however that it means a hell of a lot more to me now than it did before.

Coil may have a crack in the top of it, causing a spark leak.

And no there are no cracks, i replaced it with another good coil just to make sure and it did the same thing last night but today it did not arch at all.

I know you said you ran a good ground to the body, but what if the grounding from the body to the battery negative is lacking? Might be worth a shot...
