I am having my gauge drop to nothing at idle with just a little gas it comes back to normal. Was doing it a week ago, stopped and got an oil change problem stopped for 5 days. Just started back up. Help!
Mine has done that before the only thing is ur not actually losein oil pressure cuz if you were the truck would not run cuz oil pressure works the injectors! My best guess is the oil sending unit. Mine has only done it twice so I haven't worried bout it.
