Question about some engine readings that are in the ! range. I can't find any info online in English as to what issues they are potentially showing me. Is there some preventative maintenance I should be doing here to prevent a big bill or breakdown later?
No error codes were stored, and the chugging under acceleration at 2-3k revs I had experience before has gone since I reset the engine adaptations. There was a very loose spark plug when I did the plugs in January.
As I found it.
Google spider: Air use of the Idle Control Valve, Engine Load
I then reset the adaptations.
