94 ford f150 continues to accelerate after the break pedal has been released. It will speed up 5-10 mph (or until it shifts gears), stay at that speed for 10+ seconds, then very slowly decelerate. The check engine light is not on. What could be causing this? My first guess is a vacuum leak but I don't know how to find one or if there is something else I should try first.
