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!!!!!!

Welcome to the club. I have to agree with the others about the cat being plugged. If its the original cat I'm sure its plugged up some. Cut it out and see if your power comes back.
