Hello sir, Figured I'd give everyone a update. Shop called me and said when someone did the timing cover they messed up the crank sensor somehow when they installed the oil pan and timing cover. I had a shop do the pan and the cover, the irony. I had misfires before that point, but they seem to know exactly what they're talking about. They said something about the crankshaft too, can't remember what. I know how scary that sounds lol, The sensor how it was installed, a wire to the sensor, and that's about it so far. They're still figuring out the o2.Some random unorganized thoughts…
Try graphing the trims to see how they trend when given more throttle. A vacuum leak would usually show positive trims trending to zero with increased throttle - not what you have, though.
Bank 2 looks to be somewhat more of a problem child than the other, and the bank 2 downstream O2 sensor is switching - implies a catalyst issue. A graph on that would help see how it compares to its upstream counterpart.
But, I’m not sure if a clogged converter would cause negative trims (oxygen sensor is reporting too much fuel so computer is cutting injector pulse time to reduce fuel). Hmm. Usually that’s a leaking injector but a valvetrain issue may be another possibility? Sticking valve or lifter maybe? Maybe others can chime in on that?
Have you done a compression test?
Definitely swap the two downstream sensors and compare the voltages. The bank 1 sensor looks to be dead and your testing looks to show good circuitry.
