My 1993 Buick Lesabre somtimes accelerates on its own. Sometimes it does it as soon as I turn on the car, it sounds like if im stepping hard on the gas. Other times it happens after I have been driving for a while, when I have to break I have to step on the brake hard because it wants to speed up, and it wont stop until I turn it off again. Someone told me that one of the vacuum lines connected to the throttle body could be damaged, so I checked and a couple of the rubber elbows were badly cracked so I replaced them. But it's still doing it. What could be the problem?
have the same problem?
