i agree odd timing but im not ruling it out as it runs the cam & crank sensors. both were put in with care & went together smoothly. the computer has been drowned many times but not in last year or so. computer & map are only things i havent tried

Unhappy

lol it has old cap & rotor on it now as well as old cam & crank sensors, as well as the idle air control. none changed the running rough so the old part was put back on. only new parts currently on it are flex-plate,plugs,wires,header.

Good spark and the fact that it actually starts usually eliminates the CPS. The TPS could still be the issue. And you said ALL vacuum lines are fine, meaning the MAP line from the firewall to the intake manifold is ok. All injectors were hooked back up correctly?

Are there any strange noises coming from the engine when it is running?
