1997 Ford E-350 Econoline Club Wagon XL HD 8 Cyl 5.4L
the van hesitates after 45mph.
when cold runs fine,after reaching operating temp,and cross 45mph it starts to hesitate,if press the gas pedal,it would pick up and run until desired speed and when starts to cruise the vibration or the hesitation comes back ,but when cold it runs without, the hesitation.the check engine light is not on (it works) I took it to autozone and they scanned it the came up with #2 cyl,misfire I changed the spark plug coil and injector (with a used on from a working van) but the problem is still there.
