I know nothing about measuring threads.

It is much smoother with the engine running -- unfortunately, until now, I didn't even think about pulling it out prior to shutdown to avoid the morning stiffness.

I have not had a chance to experiment with the fueling, but this morning, I took my 92 GTI 8v in for a headliner replacement and my g/f followed me in the Rabbit. She seemed to have no trouble keeping up with me at 75 mph indicated in the GTI. She said the Rabbit indicated 65-67 mph, so I guess it is time to fire up the GPS and see if I can find out which speedometer seems off. I guess she liked driving the Rabbit -- she wouldn't let me drive home...

M5-0.8 is the thread size.  If you can't find something that fits, I could knock out a round knob on the lathe w/o too much
trouble, I have that thread tap available.
