Are you certain the code pertains to a single cylinder - rather than bank #1 - running too lean? The lean condition may be caused by any of the following conditions; faulty fuel injector, low fuel pressure, faulty fuel pump, cloged fuel supply or rail.

What is the specific fault code? Please post a reply with the fault code for further assistance.
