iroc runs rough with no throttle response

rebuilt the dissy and tried to set the engine at tdc before i installed it. Dont know how the car ran before, i got it not running. Anyways, it will start with pumping the gas pedal but runs really rough for a few seconds and then dies. There is no throttle response but pumping the throttle keeps it at idle. Its an 87 model.

Re: iroc runs rough with no throttle response

okay the timing was way off. Still have no clue what it is at but i got it running pretty good. It does however idle better with the maf unplugged. The throttle is very sentive now or the tach is off. cause i can barely touch the throttle and it will jump up to about 3500. any thoughts?
