Had a code come up on my 991 3.4 , code reader came up with system too rich bank 2 . Car starts fine, idle can be a bit rough at times and the car a bit sluggish on light acceleration however when do so a bit more aggressively seems fine. Any suggestions or clues appreciated. Though the car is going to my local indie at end of week for a big service plugs etc.

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.
