Hi,Everyone i have a 2003 f150 heritage 5.4L with 52,000 miles on it.I have never had a problem with it until today while i was driving with the ac on. 55 mph it all of a sudden it seemed to lose power like either the transmission was stuck in overdrive or was slipping when i gave it gas the rpm's wouldn't go up but the motor didn't seem to idle rough or anything.I pulled to the side of the road shut it down popped the hood checked all hoses i could see started it up drove 15 miles home without a problem. Did something get stuck? I usually drive only 1 or 2 times every 2 weeks. Any ideas on what could have caused this.

Thanks for any help!

 

OH! forgot to tell you no check engine light came on transmission fluid was changed at 48,000mi and is full.I just checked under the hood and the only thing i can figure is throttle body may have stuck.Has anyone else had something like this happen?
