So my '04 F150 V8 keeps revving up all by itself for no reason at all. It happens when parked or going slow speeds..

There is always a reason. check the onboard computer with an OBD code reader and you'll find probably a smog control device that can't make up it's mind.

sounds like you could have a vacuum leak.

It only does it every once in a while.... not all the time if that helps. Thanks guys

your cruise control switched on? somehow, just that the throttle is being pulled by unseen hands....oooo...mysterious,...maybe not! is what I'm thinkin'-

check your throttle cable mine was messed up and was doing stuff like that then replaced it and all was good

it has an electronic throttle body no cable.

...well then one of us is going to have to check on 'how to diagnose a TPS, then'.....race ya-

Throttle position sensor and/or vacuum leak. Maybe a bad PVC valve if you have one.
