Running Rough/Down on power
Ok, my truck had been sitting for about five months prior to me getting it. It ran rough when I started it (was being started once a week while stored). The truck seems to run roughest between 1500-2000 RPM. I replaced Plugs, wires, cap, rotor, coil, o2 sensor, fuel filter and set timming. It had about 1/4 tank of fuel which I figured could be the problem so I filled it up with fresh fuel and saw no change. It's better than before I did the work but it's still not right. Oh yea, fuel pressure is at about 36psi. Any Ideas of what to do next?

I was thinking injectors, could have gotten gummed up by the bad fuel. Haven't done a compression test yet, but no smoke/blow by. Pulls over 50"s of vacume.
Thanks,

Your truck might get better by itself when it will run out of old gas (i think you've only added some, not replaced). I agree with NGM about the compression test - just in case.
