I would like to thank all of those that have replied the turbo bypass valve was leaking robbing vacuum from the 2nd air injection solenoid not alowing the combination valve to open fully causing the po411 code. Trouble codes: po411 (Secondary Air Injector Incorrect Flow), po139 (Oxygen Sensor Circuit Slow Response Bank 1 Sensor 2), p1118 (Man. Controlled Fuel And Air Metering), p1198 (Man. Controlled Fuel And Air Metering), p1432 (Man. Controlled Auxiliary emission controls).		 5
