when i left off the accelerator, but it is still in gear, i sometimes get a small surge or engine jerk. it wont happen when i have the accelerator pedal depressed. i have changed out my main fuel pump. i notice the the accl. cable connected to the throttle is damage(plastic or rubber damage). could the cable be getting caught, because sometimes i notice that when i press the clutch in the rpms take a little longer to come down to idle speed.(like it is getting stuck).
