My 84 K-5 is giving me issues. It is barey idling in park or in gear. While in park, it doesn't respond to giving it gas like it should and when I put it in gear, it drives ok for about 20 feet then I have to give it more and more gas to keep it moving. It won't really accelerate at all. With the pedal all the way down on a flat road, I'm going 30 mph and I'm heaing a lot of popping sounds.

I replaced the fuel filter, plugs, cap, rotor, and wires. Fuel pump is fairly new, catalytic converter doesn't seem to be plugged. Is it a carburetor problem??? It was lacking power for about 2 months when climbing hills, but not this bad. Aside from the lacking power, this problem started all of a sudden one night.

The vacuum lines are a mess, but they are the same as they were when it was running good. HELP!!!!!!

Sounds like cat is plugged, you say it "seems" O.K., how did you determine this?
