Hello and Welcome to Justanswer, My name is XXXXX XXXXX I am here to try and assist your with your question
I had the codes read by Advance Auto last night and the young man must be new or usinf out-of-date codes as he said he had never seen these codes before. I need to get this vehicle back right as I am losing fuel mileage as well as the agravation my wife has as she does 90% of the driving. Thanks!!
this is a complicated diag and a professional like the dealer needs to preform a pinpoint test to resolve the concern
these are the possible causes above
the most common problem is the throttle body
it is electronic wireless system
I would start by replacing the throttle body first
