Hey guys,
Have a 2006 Milan Premier 2.3L I4 with the 5M. 0 modifications done to it. CEL is on, and error code is P0171 Left bank lean. I assume it's probably the MAF needing replaced but not super knowledgeable on this motor yet, and figured I'd tap into your vast experience to make sure there are no other crazy things I should expect from this engine. Tried cleaning it already with no changes....any suggestions would be appreciated. Thanks!!!
