i recently took this truck to my mechanic to resolve this problem
he checked fuel pressure
fixed 2 oil leaks - oil pressure up now (good)
plugs wires
he couldnt figure it out

thats why i posted this question

well i fixed the problem

what kind of retard mechanic doesnt check the distibutor cap
all the pins were rusted big time - like 1/16 of an inch rust barely making contact

my cylinders were flooding out half the time in lower gears
i think ill change mechanics

thanx for the replys even thoughg no one did
