Rough idle and sputtering/hestation when accelerating
The vehicle is a 2006 ford expedition 5.7l 4x4 with
144k miles. When I first start it up it will run fine
and accelerate fine until I get around 30mph then I
get a power loss and the hesitation. After that
when I stop the idle is rough and sounds like it
might be misfiring.
check plugs and wires , scan for codes even if the light ain't on
When i first crank up my 2003 ford expedition 5.4 it run rough. I take off and accelerate and when i get to 30 miles an hour it bogs down and then it dies on me what can it be.
