You got the p0521 code with gauge at half? Mine is at zero, even after the previous owner changed the afm plate and sensor. Any ideas on what else to look for? I'm replacing the oring and pump next. Can you run it without the screen? The previous owner left the used screen in the glovebox.P0521.........
I have never wanted to punch an automotive Engi-NERD harder in my life.
Screen was pretty clean considering some I have seen
Cleared the CEL and it the oil pressure on the vague excuse for a gauge in these trucks reads close to what the mechanical gauge i put on for testing said.
