Thanks, Johnny. So using that listing from Randall, here's what the codes I pulled note:
P1117 Oxygen Sensor Heating 1 After Catalytic Converter - Below Lower Limit
P1121 Oxygen Sensor Heating 2 After Catalytic Converter - Below Lower Limit
P1124 Oxygen Sensing Adaptation Area 1 (Cylinders 1 - 3) - Rich Threshold
P0140 Oxygen Sensor After Catalytic Converter (cylinders 1 - 3) - Interruption of Signal
So if I'm understanding this right, it all seems to be on the 1-3 side of the engine. That "Rich Threshold " code has me wondering, though. Is it reading rich because the other side is reading lean? Either way, aside from checking that the connection isn't just loose on one of the sensors, what could I be looking at here?
