what the heck is engine failsafe mode?
06 5.4 3v truck w/63k on the clock.
driving to work this morning over a narrow bridge suddenly I hear a ding. I think its the gas warning but look anyway. it says "engine failsafe mode". then I realize I'm losing friggin speed on this bridge...in the middle lane.
I try to rev it and nothing so I toss it to neutral and turn the key off real quick and back on and nothing. hit my emergencies and get over as much out of the far lane as possible. get to a stop and I toss it in park, turn it off, wait a second, and then crank it up and it cranks like nothing is wrong.
then I finish heading into work in the right lane just in case. no more hiccups.
what is this mode thing and what does it mean? I'm going to try to research it some more today but I'm at work and have limited time so I figured I'd post here first just in case.
