Hi all,
Here is a strange one:

Fault codes P1128, and P1130 ( Enrichment limit)

Fault codes P1123, and P1125 ( Lean limit)

How can it be both?

Also:

P0410 Secondary Air Injection, Signal Implausible Cylinders 1-3

P1411 Secondary Air Injection, Signal Implausible Cylinders 4-6

I would suspect a common problem, but not sure what

Any thoughts

Thanks
