It sounds like you are pulling on the throttle cable. There are no electrical components that would do what you described. With the engine off, have a helper pump the gas pedal while you watch the item you pulled. See if it moves.
As far as the power issue, if the engine is revving and you are not gaining speed, it sounds like the transmission is slipping. Have you checked the trans fluid to make sure it is clean and full?
Is the check engine light on?
