Experience speaking - take a look at your air filter, air filter housing, and all the associated connections. Had identical problem - was on road and figured I would check it when I got home. Then about a week later the check engine light came on. Pulled into an AutoZone with a diagnostic code analyzer. Code indicated oxygen sensor(s). But gal suggested I pop the hood and we'd take a look. Sure enough, the air filter housing clamp to the intake host had separated on the underneath size. A screwdriver and dirty hands was all it took to fix the problem. Best of luck - don't know how long this has been here, but saw it when I was searching for trim paint code on my Moby Dick.
A malfunction has been detected
Overdrive is the normally allowed position ( it won't shift into overdrive until the speed is fast enough )
Overdrive ON is the normal position But if you are towing something or driving in hilly country where the transmission is constantly shifting from overdrive to drive , then you want to switch the overdrive off
Only if you want to shut off the overdrive feature , because overdrive is the normally allowed position
Anytime you don't want the transmission to shift into overdrive * if you are towing something , or if you are driving in hilly country where the transmission is constantly shifting between drive and overdrive , you can use the button on the end of the gearshift lever on your 1998 Ford Expedition to shut off the overdrive ( the word OFF will light up on the end of your gearshift lever )
" lost battery feed "
get a new one
overdrive shut off
It means you turned it off, usually a little button on the end of the shifter.
Check engine light is out
change the bulb out for the brake light and that fixes the problem.
There is a switch on the light it seft. Off/On/Auto.
