Thanks, so the CCV breather outlet can be rerouted without triggering the computer? Great! The good news about my car is that the little old lady PO has been running Amsoil diesel rated synthetic in the car! I think a few high speed trips at 80 mph + and a tank of B20 should clean out the system, perhaps some Lubro diesel purge but I would think that would be unnecessary after the B20. I will most likely pull the crossover tube right away and see what I see and should be able to look into the IM this way for inspection. Any other tips? Thanks!
