I picked up a 95 K1500 with a 350 auto last month.After the truck has set for the night and you start it up it misses real bad.Bad enough to shake the whole truck. You have to give it gas until it has run for a few minutes it smooths out and you'd never know it did it. I changed the plugs and it has gotten worse. I will be replacing the wires soon also. Anyone have this problem here? Could it be the cap and rotor? I thought I'd ask before I started changing everything. I don't want to change stuff that don't need to be. Thanks for any help in advance.

That sounds like it could be a fuel issue. I would check your fuel pressure on the passenger side fuel rail there should be a schraeder valve you can put a guage on. Also see if you can hear the pump prime when you turn your key on or you can check the prime hole with a test light in your fuse box.
