its never to late

my local parts suplier is who I ordered them from

I do have fuel and oil to the heads

I am gonna see about shiming up the injectors until my new ones get here and see if there is any differnce

---AutoMerged DoublePost---

found the hard starting and rough running under load driving and lack of power

#8 injector had no oil out the spout so i shimedit up and man what a differnce fires right up and makes tons of power

still a bit rough at idle but other wise awsome

---AutoMerged DoublePost---

ok after a bit of research here and around

I have a new question about my rough running

when I looked under the drivers valve cover I noticed there was a injector that looked newer the the rest so I wrote the part numbers down off the newer looking one and the older ones

the newer one is a #AD1831551c1

the old ones have a #AA1816187c3

from what I have read online the AD is a split shot and is 99 and newer and the AA is a single shot meant for my truck

so could this be the cause of the rough idle ?????

Your truck is made for AA NOT AD so thats a problem change back to AA should clear up also really scope out sub harness to injectors
