I bled the hydraulic clutch yesterday and didn't see any bubbles. Did some 1st gear runs and the problem didn't reappear, so I was little pleased. But the clutch chatter and vibration in the clutch pedal are still there.

Toukna, thanks for the reply. New clutch huh? I was prepared for that so I'm not surprised. Kinda disappointing since the clutch doesn't slip and is fine otherwise (I'm not hard on clutches, I got 220,000 miles out of my first clutch in my CRX). An independent Honda place wants $800 (new clutch, pressure plate, throw-out bearing, pilot bearing, resurface the flywheel).
