erratic50,
When I said it ran "great" when fully warm, I guess I should have said "better". I think the problem was still there, it just got masked because the entire A/F curve shifted richer. For the record, it is extremely hard to drive and watch bouncing numbers on a display mounted in the center console. At some point in the future I plan to purchase and install the Aux-box to complement my gauge in order to datalog meaningful data and be able to review it after driving.

Mike,
Thanks for all that. Was about ask about locating the e-bleeds then saw you added the second post. I assume MAB will need to change?
