. . . 5" from wall to back of GO pedal is normal setup/measurement . . . look down thru floorboard where GO pedal and MCOR input shaft mate . . does MCOR shaft begin to rotate when GO pedal is depressed? If GO pedal travels with no response from MCOR input shaft, you may have wear at the mating surfaces . . . try putting a shim between the two surfaces (like a thin washer, etc) and see if that improves pedal response . . if it does, replace GO pedal and MCOR input shaft (about $30 total at CC dealer) . . .
