I have a 1994 1500 with a 305 automatic. The throttle pedal is hard to push off idle but after idle its fine. I have disconnected the cable at the throttle body and the cable moves freely and I don’t feel anything binding in the throttle body. The throttle body return spring is very stiff and as a temporary fix I have installed a spring pulling opposite the return spring to lessen the off effort required to move the shaft, dangerous but effective. Again this only a temporary fix. Has anyone else had this problem?
