-85 Tercel runs bad, 3A engine

The car runs well at idle, but jerks a lot when driving in all gears. if you suck in the vacuum hose to the distributor, the arm does not move, but it can be moved if you press the plate, but can a bad vacuum bell/membrane make the car jerk so much..
I just bought the car..

I would confirm timing and good fuel delivery/carb function for starters.

The “condenser” on the distributor? Good to know, glad it is running better!

Hi Jonas, does your distributor have breaker points? Bad condenser sounds to me like a distributor with breaker points.

Yes it has breaker points, and everything was perfect adjusted, but still runs bad, but when I put a new condenser on, it runs perfect, before it was like someone put the car on and of in superspeed :lol:
