OP teflon24V CEG\'er T Joined: Dec 2002 Posts: 67 Minnesota	I had my CEL codes pulled and they were P1131 (Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No.1), P0133 (Upstream Heated Oxygen Sensor circuit Slow Response - Bank No. 1), and P0174 (System Too Lean - Bank No. 2). Is the upstream O2 senser causing Bank 2 to run lean, or what could cause that? Thanks for any input Been shinin' like a diamond, gettin' passed as coal
