Hey homies, its been months since I've drove all because of that same old n.c.n.s. problem. Long story short, it ended up being that stupid ground wire on the thermostat. The copper wire had rusted really bad from coolant dripping on it and gas when i changed my fuel line and intake manifold. It was a easy fix but hard locating the problem when it's so many things that could stop it I'm starting. All I had to do was clip the ends of the wires and reconnect them.
