Seems to me like an opti or misfiring problem. Severe btw. Check that the wires are connected correctly because it may be firing the wrong piston at a time.

Deff sounds like a misfire, do you have insulator boots on your wires. I know i burnt up a couple with my pacesetters. Also may be an opti problem, you may have knocked the connector out so check the wire that plugs into the top of it.

(P.S. I have an brand new AC Delco https://ls1tech.com/forums/showthrea...ight=optispark , if you find out thats the problem pm me)
