I've searched, but nothing i've found helps.

If i depress my clutch pedal approx 1/4 of an inch, not enough to disengage it but not quite all the way out, i have this vibration in the pedal... it's present in all gears and in neutral. If i put the clutch pedal in, it goes away around halfway in, but comes back as soon as i let it back out. The vibration frequency increases with engine RPM. Any ideas? it did it before i installed a SPEC stage 2 and D&D performance T-56 and after.

Also, if i'm in any gear, and i hold a steady speed between 1500 - 2000 rpms, the car seems to jerk back and forth slightly, like a mechanical error somewhere. The RPM's stay constant, but the car goes ahead slighly, then back, forward back.. like a little teeny mini-buck....


Any ideas would be greatly appreciated! Car is described in the signature, and has around 107,800 miles on it.

Thanks in advance,
Tim
