07 S6, B1S1 and B2S1 Rich/lean code
Finished putting back together an 07 S6. New HPFPs due to low pressure, wouldnt run over 40 mph before. Now it runs good, great power etc. But just had B2S1 lambda rich, and B2S1 lambda lean codes pop up. Also B2S1 slow to respond.
It has 8 brand new bosch lambda sensors. Only thing not replaced were the injectors.
-Is it possible I switched the connectors for B1 and B2? If so this would suck as the connectors are not accessible with everything up in the car !
-Without just throwing new injectors at it, can I check somehow it is the injectors? Havent checked fuel trims yet will check tomorrow. Short term fuel trims should show if its an air leak too.
Just spitballing while Im stuck at work for the day.
