Hi guys,

I'm stumped here and could use come help. Recently had downpipes installed by a friend and I started getting an SES light and code 2C32 - DME: Lambda Control 2.

Upon researching it I figured it was pre or post o2 sensor on bank 2.

I ran a third gear log to confirm and the AFR in bank 2 jumps right to 234 on decel but in bank 1 it hovers around 60.

How can I have codes for bank 2 but actual issues with bank 1? Just trying to determine which o2 to replace. Or I'll just end up doing all 4.

Also, replaced all injectors with index 12, properly calibrated.

Thanks,
Mike

Did this happen right after the DPs were installed? Are you positive you did not get the 02 sensors backwards during the install? This is a very common mistake.

I didn't install it I had a mechanic do it. He claims they weren't mixed up, and I think if they were mixed up I'd get specific DME codes on both banks for them being swapped
