why didnt you run the intelt and throttle body, thats gonna have some effect
its only extendning a few wires to get soem of the censors to meet
although i doubt this is your problem as i know of a few klze conversions that have done this to save space

See what comes up, I wouldn't rule out that filling up may have coincided with another problem. Was the engine sitting long before you had it installed? Do a compression test?

When you say holds back, is it misfiring? Dizzys are crap on these cars, I think my second one is on its way out…
