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?

remind me, was it modded at all? I bet you are just running lean after you warm up. After my 2056 I had to retune the MPS and change the ECU idle mix. A quick test is as mention above, just turn the knob on the ECU to richen the idle mix, if it goes away then you know that is your problem and you better take a look at your mix across the board before driving it much. Don't want to drop a seat/burn a valve etc.
