hi ford lovers from raymondoson
2005 ford 6cyl ba sr
finally solved my 2005 ba run like crap mystery , yep you guessed it a rusted out fuel rail.
in my opinion if your 2005 or even later don't bother with injectors being the problem or the like , just remove the fuel rail , clean the entire fuel system (including those injectors) ditch it and put in a new one because when they rust out from the inside all the crap heads straight for the injectors and clogs em up and possibly does damage.
fuel injection systems same as diesel systems must be pristine clean otherwise they run like crap.
common rail diesel systems if fail just head straight for the bank manager to pay off the loan you need to fix it !!
i have read what everbody has to say with quick fixes but the only way is to strip it and see for yourself !!
remember back to basics will generally reveal most issues
the follwing pics will shock you
