QUESTION: kk so it said it was open throttle position switch circuit..i changed the throttle position sensor..still doing the same thing..i turn the car on revs high 3000-3500 and stays there..after a bit.no engine light on..slowly revs down to normal..say 900..if i take it aroudn the block, while driving, it will start rev higher and drive itself and want to pull and move forward, even if im pressing on the brake,,it i put it in neutral and back into drive, tranny will pull hard and clunk..would it be the bad circuit or maybe a leak somewhere in one of the hoses
