Strong hesitation when I tried to accelerate to a higher speed
I have a Ford F150 XLT superb with ecoboost. The truck accelerates smoothly
to higher speeds, when shifting at normal speeds. However, when I punch the
gas, the truck strongly hesitates and the engine lights goes on.I have had the
spark plugs changed, cylinders chambers check and no deposits, Has anyone
experienced this problem? My mechanic who is a ford guy did all the tests and
still couldn't find the problem.
