'99 F-250 With Error Code 1391
My 'Service Engine Soon' light came on a few days ago. I checked it out with an Actron OBD II and came up with the code 1391. The Ford Motor Company's code definition says, "Glow plug circuit low input (Bank 1)".
Anybody know what this means? Do I just need to replace the plugs, or is there more to it?
