Why does my F150 sputter and sputter at acceleration?
Why does my F150 sputter and sputter at acceleration? I changed all four o2 sensors and still the same thing i cant get a diognostic because the engine light wont stay lit but it does blink perodically then goes off it sputters bad at acceleration and very rough idle also loss of power Why does my F150 engine have rough idle?

Find and repair misfire on # 1 cylinder, also check for vacuum leak on...
