I would smash the throttle, engine would rev like normal, but I wouldn't accelerate and the truck wouldn't shift correctly. Ford checked it out yesterday and they found absolutely nothing wrong with the tranny or engine and there weren't any codes to speak of. They ended up revving the engine while in park and noticed that the air intake tube was collapsing which was starving the engine of air hence the massive loss of power and shift issues. The techs along with service manager told me they have never seen anything like this and that they suggested I replace the tube along with the air filter for a tune of $300ish. I said scratch that, I 'd rather grab a CAI from JLT for far cheaper. I mentioned that if the problem persists then I would be bringing it back for further diagnosis as my powertrain warranty is good for another 10K miles.
Damn that’s odd Dip. I need to get mine in one of these days. My wipers when used you have to cycle the multifunction switch a few times or the wipers won’t turn off. They won’t turn off just turning off the normal way.
I did some research the last gen of the steel F150’s had a tsb for this but 15 plus are excluded.
