So, now that the car is running and the weather is nicer I can finally drive my DeLorean. However, there's a hesitation when I accelerate from a stop and occasionally when I change gears if I let the RPMs drop.

The trigger seems to be about 2,000rpm. Above that mark and the engine sounds great, below that mark and the engine sputters and lacks power and RPMs slowly climb. It doesn't seem to matter if the engine is warmed up or completely cold. It also doesn't seem to matter how much gas I give it with the pedal.

Looking to solve this problem but I'm not sure where to look. Anyone have any good experiments​ to try to figure out more details? Or maybe someone knows exactly what the culprit is...
