So I got a job and one day got a little bored after work and decided to tinker with this thing again and see if I could figure out what was wrong with it. Started withing unplugging coils, one half of the engine was unaffected whenever I would unplug them....so I test the power to the coils and it checks out. So I decide to move on to fuel, check the fuel pressure and it checks out. But I was bored and decided to tear the car apart and check to see if either A) the rail was clogged or B) see if the injectors were getting power. So I pull the rail and injectors out and there is some fuel loss but nothing crazy. Since I am bored I pull of that little silver cap (on the passenger rail that says DO NOT REMOVE) and right after I pull back the tabs all this gas comes spewing out of that side of the rail!
Fast forward to a few days later (today) I have a day off work and decide to go to the yard, get a new fuel rail (I kept my injectors), and install it and see what happens. Get everything installed and the car doesnt wanna start, so the next time I give it some gas and it starts on up with a huge hissing sound, so my first thought is oh damn I forgot to clean the upper intake plenum gasket. So I tear it all apart, clean it up, and install a new one. Go to start it again and bam! Thing starts right up and idles nice and smooth! Well it has a very slight roughness to it which I may or may not look into but the thing is running on all six again! Take it out for a drive and the thing is even shifting and down shifting better (where before when I would start to come to a stop the idle would bounce all over).
So the way I see it is that my misfire was caused by the fact that the silver cap was probably holding a vacuum causing no fuel to get to the passenger side of my engine. So moral of the story is......just because you have good fuel pressure does not mean that there may not be a fuel issue.
Just figured I would put my results up in case someone else runs into something similar.
Problem: Passenger side of engine misfiring
Solution: Replaced fuel rail with junkyard unit for $13.
