help please

once again my truck is all mest up, it has to be the carb....

ok it was driving fine today, i get home and park it, it cuts off before i get a chance to do it.....so i crank it up 10 miniutes later cuz im bout to go out. and i get a little down the street i let off the gas and it cuts off again. any ideas? it will idol when i crank it up, but once my foot touches the gas and i let off, no matter how much it will shut off.

u got a weber? pull it off and re-goop the gaskets. if not, then i'm guessin a vac leak. mine kept burstin the vac caps i put on the intake mani.

its not a weber. but ok gonna check my lines, but this has happened before, i just dunno what to do

there is two vaccum lines under the intake that like to pop off sometimes..check those and also..pull,check and clean your EGR..sometimes they get carboned up and stay open also doing exactly as you described..hope this helps!!
