2005 Malibu Maxx
My 2005 Malibu Maxx LS is using twice the usual
gas, clugs at stops and has reduced power and
acceleration. No codes thrown. What could it be?
Then your going to have to have the vehicle live data scanned, it sounds like one or more sensors are sending a misread to the computer, as the computer sees the sensors change readings even though they are incorrect, it thinks they are good and won't set a code.
