I noticed that the throttle pedal went to the floor without full acceleration. The car still accelerated so it was just a curiosity for the moment. Since the car would be idle for a few weeks, it went on the battery charge maintaining device. I noticed that the throttle cable was no longer on the tension wheel. I put the cable back onto the wheel. I surmise that there is too much slack in the cable. How do I adjust the cable in order to remove some of the slack?
