k5 running like crap

[z71MudDog]

sorry for the re-post guys my other post wasnt bumping

 

my k5 sounds bad it has such low idle that it dies out sometimes and when i try an mash on the gas pedal to burn tires it bogs out like its drowing or something...an the mpg has dramatically decreased:i chenged the inline fuel fitler thats in the carb changed the air filter the plugs and wires ran ok for a few days but its still doing the same thing.and when im going about 30 mph or any speed really up a hill it chugs very badly i have to put it into second for it to have more power
