Sounds like you took it to NissTech! lol
I dont know where you are in SC, but if you have future problems and cant figure it out, call this guy - 828-287-0159. Ask for Little Charlie, he does good repairs very cheap. Cheap as in he pulled my motor from my z31, pulled the crank, had it turned, reinstalled with new bearing for like 600 and some change. Changed my timing belt and put in a new clutch for 700 and some change. Good guy that does good work cheap.
