Pulled these codes:

P0171 Fuel Trim System Lean Bank 1
P1151 Lack Of HO2S21 Switches - Sensor Indicates Lean
P0155 Heated Oxygen Sensor Heater Circuit (bank 2, sensor 1)
P1000 OBD Systems Readiness Test Not Complete

This car is confusing the hell outta me. I know I turned off the downstream o2s!

And the upper o2s are brand new!

Now among other things I raced my buddies BMW and he pulled on me! He has no mods done to it and I was beating him in my old 2.5L!

BAAH!

Why would bank 1 be showing lean when it's the bank 2 front oxygen sensor that is faulting?

Are the rear o2's atleast plugged in? I know I turned mine off, but didn't have them plugged in and it threw a code or two.

Though some how Heath @ MM was able to totally turn them off and my EGR system and not have to have them plugged in to stay CEL free.

Time to get a wideband on there and see what's really going on

Sounds like trhe front upper O2 (both O2 codes are for that sensor) isn't even pluggen in or something.

One bank will compensate for the other and throw an opposite code. The trims will be complete opposite ends of the spectrum.
