nope, had nothing to do with the neutral safety switch lol (safety swith was my best guess) it was a combination of wrong firing order, mixed plugs and my dumbass friend saying he put the rotor in the dizzy but in reality he had no idea what a rotor was, so he did nothing. it idles great but has some hesitation when you hit the gas.im about to set the tps and timing now and then wire up vvl
