Focus wrench light and chugging!
I have a 09 focus with 57,000 miles doing the same thing. I took it to the dealer and they said that no code was stored in the computer. They drove the vehicle and could not duplicate the problem. Charged me $75 and sent me on my way. The vehicle losses all power, pull over turn off and then turn on and it drives fine. The vehicle also is chugging at highway speeds. I have had my vehicle at the dealer now for two days and guess what they can't duplicate the problem so nothing is wrong. They have a TSB for this issue which states it is most likely a throttle body. Thet read it to me! They don't want to replace it because they have never had to replace one before. This vehicle is under warranty. I am totally frustrated at this point and I ready to get rid of all 3 of my ford vehicles. Any suggestions!
