My brother (an auto mechanic in Florida) thinks the throttle clip on my Century is broken or malfunctioning. The car will drive for awhile but then when I engage the pedal the car will rev and sometimes go forward but then not other times. He really thinks it is not the transmission. I have 200,000 on the car.
