"tuning fork" vibration in pedals

My 02 6-speed (4/02 build) with 128K has developed a "tuning fork" vibration in the pedals--just enough to put the bottom of my right foot to sleep after a half hour of driving. Vibration is present when the car is stationary, and kicks in at about 2200 rpm. It may be that it's only present at higher temperatures, although that's hard to know given that it is always hot in the desert in the summer.

I have driven an 11/01 build (with 75K) and a 2/02 build (with 115K), and both had way more vibration through the floor and the console, but their pedals were completely dead: no vibration at all. Two indies have agreed that it's not the fan, fan clutch, flywheel, or clutch, but they are otherwise stumped.

Any ideas? Thanks much.

get on m3forum.net as the're all the e46 guys. I do remember some vibration through the clutch pedal on my e46 only felt if you're foot was just covering the pedal..

Maybe motor mounts?? Or guibo?? only cause of the miles on your car

Thanks for the suggestions. Forgot to mention that it's not mounts--those were the first things replaced when the vibration appeared. The indies don't think it's guibo in light of the characteristics, and they've tried just about everything, so I tend to trust them on that. And I've been over at m3forum since I bought the car in '02; I just thought I would broaden my search after I struck out over there.
