Reply to "Crossfire from MSD 8253 Coil ??"

** Update ** The problem is resolved. Carefully rerouting, separating, and inulating the plug and coil wires fixed it. It looks wonky at the moment but misfiring is gone.

Answers to Marlin's questions:

The symptom was popping out of a couple of the passenger side throttle bodies when accelerating. There was also sporadic dips in the idle. Both of these symptoms are gone.

1. Holley Dual Sync distributor. It is needed by the Terminator X ECU.

2. Blackout Test - Yes. I coincidentally tried it early this morning when it was still dark. I could not see any arcing.

3. #5 and #6 seem okay. I think most of the problem was on the passenger side. There was popping out of a couple of the throttle bodies.

4.It is probably okay as is. The prior owner ran it that way for years.

I completely agree that electricity always want to find a ground. I think the big coil amplifies this notion.

Thanks Marlin!
