Clutch Pedal/linkage problems of the 1999 Nissan Quest

The accelerator cable on our 1999 Nissan Quest failed in 2001, we replaced it, and now in 2005 the cable is failing again. The accelerator pedal "sticks" and you have to push very hard to get the vechile to accelerate, creating an unsafe situation where you often have to accerate too fast upon takeoff. This could lead to a rear end collision.
