Running the truck on it's 2nd break-in.
Running between 2500-3000rpm.
Getting code 44 (lean exhaust).
I assume I need to increase fuel psi at regulator. I haven't set idle timing yet, I was going to get her broke in 1st?
I thought my Maddox gauge said 14psi at location just past fuel filter...
I have 1986 c10. 4.5/6 Mcgough static drop. Leans left 13/16th, front tire rubbing fender well. What spring spacer can be used? Part name and number of possible. Thank you.
