Completed rebuild on 1974 914 2.0 L. All fuel and vacuum lines are also new. Engine idle varies between 1000 and 2000 rpm every few seconds what could cause this?

Did you rebuild the throttle body?
Most of them are worn creating a vacuum leak Also worth servicing the distributor Or just replacing with 123 |
