Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

There is also a diverter valve just downstream of the SAI that I think modifies valve timing above 4200 RPMs. That's another great set of CEL codes if hoses leak on the way there of past the diverter valve.
This is a source reference. Confirm exact model applicability in the original material.
