ok long story short, I bought a 300zx from a friend who had tried to do a headjob on the car. When I got it it was half taken apart ( heads off)
and I pulled the old motor and installed a new one with low miles but i cant get it to run smooth, changed the plugs, made sure each coil is firing good,
Now I have never worked on these cars before and I didnt get to take it apart which is my problem...were do all the vacuum lines run specifically...?
I have no literature...no tear down expereince on this motor, I have all the plugs in right places (99% sure) and it just idles ruff and revs like it has a miss....Motor came out of running driving automatic car..and wasnt beat on!
Any advice, thanks in advance
