Having significant issues with P0154 / P0134 codes - have a constant SEL - have replaced all four 02 sensors - spliced in a different (used froim roverland parts) bank 1 front 02 connector - truck runs rough and is getting roughly 8 miles to the gallon - feels as if I have a cylinder not firing - am ready to pull the intake manifold, replace the plug wires, the plugs and the engine harness (nuke option 1), followed by the ECU (nuke option 2) if must but really hesitant as it simply can't be swapped and I don't have the gear to reprogram - guys, first, am pretty sure the harness has issues, am going to roverland to get a used harness - has anyone ever changed their entire harness? Second, before I do so are there known instructions for checking continuity?
