This is on a typhoon, scan master 3. My fuel system and pressure seem to be working and correct. I put my foot into it so the engine sees some load and the o2 goes from .900's to .080 and she pops and sputters. The fuel pressure regulator adjusts when I adjust it, and it does begin to rise when I put my foot into the throttle. So I think it's working correctly. I checked my cross counts and the number is 128....it never moves. Whether I'm warm idling or cruising it is 128. This makes me believe the o2 is shot and may be causing my part throttle/load lean issue. I want to be relatively sure before I go spend 4 hours on the truck. Ideas?
Thanks, Jeremy.
