Default Backfiring

I have a 95z25 6 sp. Stock except cam. I put 8mm Wires on it. And now im lucky if it stays running. At idle it seems to be running decent and if its cold it idles great. Could the 8mm wires cause it especially since the old 7mm wore out wires i never had a prob with?

Make sure everything is seated correctly and your wires are in good condition..

If they are brand new, and are arcing... You've done something wrong

What kind of 8mm wires did you get? Are you sure none of the new wires are burnt causing the arcing?
