Just logically speaking, if fuel pressure was low, it should say both banks are lean, not just 1. So I’ll scratch fuel pressure off. O2’s, are new, but I’ve read Bosch isn’t the best to use, either Mopar originals or NGK. That might be a cause. The MAP sensor is the last one that I haven’t changed, so I’ll clean it first. Vacuum leaks, there are none as the carb cleaner didn’t cause s high idle and I used 2 cans all over that intake. Plugs are all new, gapped at .043, and when I swapped the cam out, they looked great. Coils are new from MSD. So that leaves the injectors. I put a bottle of injector cleaner in the tank, so it’s gonna take a while to see if that will work.
So at this point, the cars runs and drives, slight pulling to the right but the alignment is scheduled for Thursday morning.
The owner can drive it home and if he has any problems, I think he and his boys could handle it.
