Re: What would cause this??? Video attached
looks like a nice find. Does it do it while driving? Not to be an SA, but I don't spend a lot of time free revving a motor so I can even say whether my my rig may do it or not.
I doubt its fuel or oil since there is really no load on it. Needs a load on it to see if it still does it. These are 'drive by wire' throttles-- I would rule out throttle position sensor, map
sensor, perhaps even the EBPV
if its closing or this is being done when its cold (which you should not be doing, but you likely already knew that...)
hell, I'd make an offer that keeps you safe from repair expense and go for it if its a nice truck.
