i still have a miss in cylinder 4 and 6 and still idles rough and i belive it could be the injectors clogged has anyone had a problem with there injectors clogged abd if so what where the symptoms and how did you fix the problem...i have heard alot of this sea foam stuff and what is the best way to use it to clean the injectors and how affective is it?

p.s ive already checked the and changed the plugs and wires, checked the coil pack and changed the fuel filter and was a bit dirty in there that is why i belive it could be the injectors...any help is great thanx

 

im actually having this same problem with my 5.0 lately. im working on it tomarrow to figure it out but i think its either the injectors or maybe a bad plugs. but it has 2 new coilpacks and wires are brand new. and the ruff idle/hesitation used to only happen every once in a while but its now happening alot. so im slighty lost but im hoping to figure it out at my buddys shop tomarrow

 

When I had my misfires, I took it to our mechanic who had a cleaner that the public can't buy. Worked great on my working injectors, but my misfires were due to the coil on the injector failing and an injecter sticking closed. I replaced both myself, not that hard of a fix with a Haynes or Chilton manual, just a lot of time.
