Misfires
P0150 oxygen sensor malfunction bank 2 sensor 1. Second code is bank 1 too lean, third code has too many digits. Did you use Bosch oxygen sensors? I did with good results. Wires shorted when pressure washed?
Glad misfire is gone!

P1171 is too lean, both banks. Looks like you had P0150 before you changed oxygen sensors. Possible problem with wiring harness (melted wires, open, poor connection.) When I did mine, I used too much dielectric grease on first plug (designed to be air and water tight) and needed channel lock pliers to fully seat and lock connection.
I had diagnosed need for new O2 sensors by monitoring their performance with Scanguage II while driving. New sensors, cleaned MAF, "German" Castrol 0W40 and I average 18 mpg. And to reference another thread, my speedometer and odometer are dead on with gps and highway mile markers.

Ya, I wondered about the wiring. I'm not sure what to do about the lean system. I've doubled checked all the lines and connectors, figure I may try the replacing the fuel filter? The odd thing is that the codes don't throw a SES light, but they show up on the code reader. It also has a rough idle in in gear, but runs like a sewing machine once you start moving.
