ive been getting really bad mpgs, usually 10, but as of late around 8mpg. and my mother has been the primary driver as i mostly use another car, i know shes not beating on it. ive done oil, oil filter, air filter changes, cleaned maf. )unrelated, but just had to replace the battery, it died while running errands and would not hold a charge later, it was the oem battery)
car has 45k miles its a 2006 3.6L.
i snapped pics of the old plugs after i changed them out, what do you guys think do they look terrible? i have no exp in diagnosing plugs.
they are in order 1-6.
