We have a 2005 Envoy I am getting error codes P0054, P0137 and P0410.
We have replacted both the 02 sensors...the downstream twice. Have replaced the air injection pump, the throttle body, MAP and MAF sensors, The CCM, electronic igntion coils.... BUT still getting these errors. Anybody got some help ??
