Engine Performance problem
2003 Cadillac Deville V8 Front Wheel Drive Automatic
mechanic changed mass air flow sensor twice ( rebuilt part), works for hour, then back to poor running, mpg, etc. His hand held meter says Mass air flow sensor problem, and right and left fuel bank. Dealer says need OEM not rebuilt part. What do you the expert think?
