Where is it jumping to the block? Can you see it happening?

 

[Doug357]

It is jumping from the spark plug wire to the block and yes you could see a blue spark Play whatever you wanna call it I'm pretty sure it has something to do with the reason why it's backfiring but can't find anything on the Web about it

Are wires crossing at all?

Where on the wire to the block is it jumping? Did you buy quality wires or cheap wires? I fixed up a Chevy v6 and used cheap plug wires. It was jumping through the plug boots. Had to go buy better quality wires to fix the problem on that vehicle

 

[Doug357]

No sir

check the ground strap to the engine to fire wall or around that area did you buy die electric grease to put inside boots before putting on the spark plug

Sounds like a bad plug wire arcing.

 

[Doug357]

Thanks
