Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

2003 C2 with 42K on the clock. I am 4th owner, car has run flawlessly for the last year putting 10K on the odo including 8 autocross events. Coming from mazda's the clutch pedal has always been what I would call stiff or tightly sprung. Last week I had my Sumi's put back on for the winter months (saving the 'stones), they raised the car up on four separate floor jacks, each placed under a jacking point. On the way home I noticed that the clutch pedal was much easier to push and I noticed some vibration when engaging. On the way to work the next morning *really* noticed a strong vibration when rev match/down shifting when the clutch is engaging. The clutch itself is working fine, no slippage/grinding of gears. No fluid leaks under car. Reservoir is full. Is it possible that the tire guys pinched something? Doesn't seem to make any sense but as Leroy says "There is no such thing as coincidence" Have searched and haven't found anything conclusive that would help know where to start or what to try to help diagnose. Hoping you guys can suggest or point me in the right direction. Thanks in advance.

Suggest yo do a search for "power spring" http://www.renntech.org/forums/topic...-power-spring/

POST 3 / ORIGINAL POSTEROriginal post

That issue caused the pedal to become "much firmer", mine is less firm . . .

POST 4Original post

Sounds to me like a partially broken pressure plate.
