Ok, thanks Mike.
I failed to mention this earlier but there is a major unburned fuel smell at all times in the exhaust.
Is there any mixture adjustments?
I replaced the O2 sensor , and I wasn't sure if that helped any, but it seemed to a little.
Another thing is. The truck will start right up after sitting overnight. But right after that, if you shut it off it is a PITA

to get going again, like it fires then dies immeditely for at least 5-6 times then it will fire and barely run. When you touch the gas peddle it will smooth right out and idle perfect.?
I am starting to feel bad that I even posted about this major headache truck of mine.
