The only thing that isn't original to the 98 is the basic engine including harmonic balancer and flex plate. We put the 98 intake, throttle body, injectors, distributor, etc. onto the 95 engine. Intake and right exhaust manifold from the 98 were installed on the 95 engine because the 95 engine had EGR and the 98 didn't.

All wiring, sensors, injectors, etc. are original to the 98.

I don't know how it ran before because the original engine had a connecting rod through the oil pan....so, no telling how it ran.

We had a guy scan it...don't remember the codes, but there were two. One was coolant temp. or something, and the other said no cam sensor signal. We installed a new cam sensor in the distributor, and it runs the same.

Rotor is pointing at the mark when #1 cyl. is at TDC.

I put a 98 Engine in a 95 before, and we just put a 2000 engine in a 94, and had NO problems...just changed intakes, etc. just like we did this time!

As far as the flex plate....that should have nothing to do with it? Basically, we have an unweighted torque converter and unweighted (95) flex plate....so, that should only just cause vibration...correct?

thanks for the help and advice!
