CEL and P1113, P1128
[:@]Got my VAGCOM dumb interface today. CEL on, so pulled these three codes - too lean, O2 sensor, too rich. Cleared them and only O2 and too lean came back. Any ideas? I have a pin hole leak somewhere in the IC because I can hear it with pressure test, but why would a leak in the intercooler give me Too Lean? Can there be Vacuum there, to suck in unmetered air, and cause Too Lean - I thought only vacuum is behind the throttle body when you let off the gas? I'm thinking a leak in IC might cause boost leak and too rich, as air escapes thus causing more fuel in the ratio. What does intermittent mean in this application?
