Hello,

I am working on a major resurrection of this 1974 914 2.0L.

I have completed changing /replacing the fuel system (lines, injectors, tank, etc), a major tune up and a reseal.

After a major tune, valve adjustment and timing - the car ran really well. I was very happy.

Started it today - to just hear it run - very rough idle when cold (this is new). It appeared to hunt between 300-700rpm - surge/die/surge/die/surge/die.

I have not touched the idle adjustment on the throttle body - it appeared to run at about 1000rpm when warm yesterday.

Cold Start Valve? AAR? Not sure where to look first. I will check the vacuum hoses again tonight.

Thanks,

Frank

Correction....The sensor is mounted in the Intake Plenum...Adjusting the rich/lean screw on the ECU made no difference...
