Glow plug lights up while driving
I've got an 03 6.0 that started this on saturday night. I changed the fuel filters in the a.m. and started the truck after i finished and all was well. Saturday night I hit the main road and started accelerating, shifted into 2nd gear and the engine died back to idle with my foot still on the accelerator, the glow plug light came on at the same time. I lifted my foot and the light went out, pressed the accelerator and the engine picked back up and ran fine. Same thing monday morning, monday evening from work , and this morning it shut off completely while warming up, then died back to idle while accelerating. Glow plug light comes on every time until you lift off the throtle.
ANY IDEAS !!
