(p2279)Intake air system leak , p2187 system too lean at bank 1 plus 2 others
I have a 2010 audi a4 b8.I have the following 4 codes. Car runs fine.
p2279 Intake air system leak
p2187 System too lean at idle bank 1
p0507 idle air control system rpm higher than expected
p0420catalyst system efficiency below threshold bank 1
I figure the first 2 are the important ones(p2279 & p2187) and p0507 and p0420 are just by products of not enough fuel or a air air leak somewhere. What are my possibilities and the most likely ones. Car runs and idles fine it seems.Thanks in advance for any solid possibilities.
