sounds like you're adjusting the distributer too far in either direction. Too far advanced will cause high rpm problems and too far retarded will cause the low end stumble. I would def have a pro time the car as you can do alot of damage with improper timing. I killed a civic that way :jump: Glad i learned on the honda and not on a real car.
Also the wires could possibly be loose or damaged inside and not helping the problem. I'd check them with a fluke meter for continuity 0=bad ~1300= good
