I had a very weird occurrence today in my 2005 Expedition with the 5.4L. I was driving around in Dallas and all of a sudden lost throttle response. I also got a message "throttle control failure" in my message box. I killed the engine, restarted it and got throttle control back. But now my check engine light is showing. I then continued my trip to Houston without event (but with a little worry). I have 78K miles on my expy and I got 18 mpg on the way home (about average for 70+ mph).
Does anyone know what happened and how serious it is ? I plan to visit my local repair guys (non-dealer) if the check engine light does not reset in a couple of days.
Thanks, Lynn
