pedal vibration

Hey Guy's,
I know this is kind of a vague question, but I get this vibration in my gas pedal....to me it is all the time. I can also feel a little bit in the clutch pedal. It seems to get worse the higher the rpm, but it is all the time and is driving me crazy. Does anyone know what might cause this type of gas pedal vibration? Maybe a motor mount?
Thanks

Things to check are rear tire balance, torque tube issues, clutch and flywheel, dampener coming apart, then maybe motor mounts. Bottom line is that the gas pedal is not even connected to anything on the motor. It only mounts to the firewall and electrically controls the throttle body. I'm sure the vibration is simply coming through the firewall or is possibly in the entire chassis. Try and gather more circumstances that make it appear and make it worse or better. Get to highway speed where it's doing it really badly and then push in the clutch and see what happens. Then rev the engine with the clutch in. Then let out the clutch and ease into the throttle and see if the load affects it.
