I assume the surging is at idle. The resonance valve should be closed. If its cycling with no codes I'd suspect a wiring fault. Unplug the motor and see if the problem goes away. If the problem...

Getting the car moving when I first bought it 3.5 years ago was embarrassing. Like I didn't know how to work the clutch. Ever stall in front of a pickup truck? Over the years I did a lot a small...

Replace Original 964 Coils

My 1990 C4 has never run very well at low RPM. I get throttle lag that I find very un-Porsche like. Sometimes the car will stall when I put in the clutch pulling up to a stop. I also needed what I...

Maybe try jacking the tire or hub/rotor a bit to swing the hub out. Might be all you need. Be careful to avoid unbalancing the car, which I assume is on jackstands.

Thanks RoadSleeper.

Just measured the stock wheel and its 15", 380 mm, so the Momo at 350 mm is just over an inch less in diameter. That plus a spacer might do the trick.
