is the check engine light on when acts up

Does it shut off on you? How does the tach act? Does it smoke excessive?

get your codes like the fellas above said to lead us in a direction....could be a bad injector, under valve cover harness...chaffed wire....we at least need a starting point for diag...

Check engine light comes on and blows oil out, puffs blue smoke and runs poorly. Won't pull itself in low lock first gear.......

Been to ford dealer they replaced 3 injectors and updated

One garage say's fuel reg or pump we are out of warr don't want someone slaming parts on then not the problem

if i was a betting man , without pulling codes , i would guess short harness under valve cover loose ,no matter what get codes pulled , go from there
