Engine Light after "Engine Failsafe Mode" Message
<HR style="BACKGROUND-COLOR: #d1d1e1; COLOR: #d1d1e1" SIZE=1> <!-- / icon and title -->I have a 2004 F-150 Lariat with a 5.4. (FYI-Have not had clockspring recall fixed yet)
124K miles. Vehicle has been operated in AZ and TX only until coming to Minot, ND 6 weeks ago.
3 days ago I got an "Engine Failsafe Mode" on startup. I shut the vehicle off immediately. Started it up again and the "Engine Failsafe Mode" message disappeared, but the engine light came on and has stayed on for the last 3 days. It seems to be running ok, maybe a little rough.
I ran the reset info on the dash screen and all systems read out OK. I have not run the truck over 40 mph since, and not on the highway, but it seems to accelerate without a lot of hesitation.
I've seen in other forums that this might be a dirty or faulty throttle body and/or the dealer may be able to re-flash with updates but this is old 2004 info from newer owners back then.
What am I looking at from a time/price angle when going to the Dealer for service? I don't want to replace a throttle body if it just needs to be cleaned and re-flashed because I'm ignorant.
Anything I should watch out for? I'm not a competent mechanic!
Thanks in advance for your help!
