lucky,
what ive done was simply pulled the pcv valve and vented the crankcase vapor temporarily to atmosphere. similar to an oil cap with a breather, and capped the intake manifold vac. line. only at idle, just to see if it were a PCV (over) flow issue or to see if it were oil vapor im seeing out the exhaust.
I take pride in working on my vehicles and not throwing in the towel to a shop unless it's beyond me. Hopefully, sooner or later my knowledge and technical advice will truimph over an unnecessary dealership visit. if i can isolate it as a tune issue, I'm going to have ECS tune the car.
