OK, before anyone gives me grief, I am doing the following to test for KR at low RPMs. I DO NOT NORMALLY DRIVE THIS WAY.

At 1300 to about 1800 RPM in 5th and 6th gear at WOT and after 1 second or so the following happens: a tapping occurs on the clutch pedal as if someone was behind it and quickly tapping towards my foot. It is light, totally random, and will do it about 3 times per second. Below 1300 no, above, no. in 4th and lower I go through this range too quick to feel anything.


What the hell is it?
