wanna say thanx to everyone who led me in all the directions of testing my electrical harnesses to testing injectors and sensors and stepping me though the whole engine in general.

If you guys know I've been dealing with a miss and a looping injector when hot, tested everything outside of the motor and all checked out fine, no oil in fuel filter housing and no fuel in engine oil. Now I could have oil in my filter houseing but I change my engine oil so often the oil in clean so I may not notice the fuel becoming black.

well yesturday I got tired of this miss and started pulling ijectors out, just recently I started to puff some smoke on the front 2 cylinders on the driver side, I narrowed this down by unplugging the pass through connector and it stopped smoking blue. Pulled it apart and behold, middle o-ring is totally messed up. the truck would run good but when the engine is really hot she would have a miss and hammer a bit on the driver side. Didnt show the typical everyday symptoms from what I;ve read but this is what I've found and hopping this will solve my issue, picking up the parts today and hopefully fixed tonight, hope to come back with good news on how its running.
