Engine kicking into limp mode.
My 2004 F350 6.0 keeps kicking into limp mode. I have a SCT tuner with the EGR delete option. I have the tune set to street with the EGR delete selection. I've had this set up for over 5 years. Recently, the truck kicks into limp mode and throws the EGR and KAM memory error codes. Now, I am unable to get the truck out of limp mode, even after returning to factory settings and then reinstalling the street tune with EGR delete set up. I was also getting random cylinder contribution errors, but they either change from individual cylinders 8, 1, 3 and 5 error codes (only 1 cylinder code at a time) or don't come up at all. The truck had to be towed to the dealer and now won't start at all.
Any suggestions?
Thank you in advance.
