Anyone have updates on this problem? My car has the exact same symptoms and the loss of engine power symbol appears on the dash. All happened after I sent my car into the dealer for the HPFP recall. The car will occasionally idle very rough fluctuating between 500 and 1000 RPM's and then die if it isn't put into gear and given gas immediately. I'm throwing codes 2CF6 and 2CF7 (throttle valve potentiometer with possibility to mass air).

I've heard others having the same problems after getting their car serviced. I'm still trying to fix the problem. I'll be checking the O2 sensors this weekend, hopefully that fixes the problem.
