my vehichle was running fine today till i got gas were i usually don't, since den my truck has been acting up. i did an oil change, air filter, n plug wires... it jus started recently dying out on me, it won't stay idling, n when i do get it to idle it will jus bog down n cut off, i did by chance get it to run long enough to get home but it seems dat if i stomp on the gas or jus gas it, it starts to sputter on me...
i had problems before where the vehichle would bog down n lack power but i changed the plug wires since n have had no probs in that manner... i also saw a small stream of white smoke comming out of my airfilter, smelled rich like oil.... right now the vehichle is in my drive way, i had a few small hose lines dryrotted away but i fixed those... i thinkin it might be the feul filter but i'm not sure... when i started havin the problems it got so bad i had to hold da brake wit my left foot n idle it manually with da gas, but even den it would jus bog down n die out.... do u have any clue of what might be happening.... i'd appreciate any advice u can give...i jus went out n started it up from bein cold an she fired right up but after a few seconds it started to idle real hard, as if it were goin to die out... i need sum good advice i can't afford to have my truck crap out....

sounds like your cat is clogged and choking off the exhaust when it warms up.

so da catalyc converter could be causing all my probs, i thought it was feul pump, cfi, egr, feul filter, bad gas but damn if its just the catalic converter i should be able to fix it... well if n e one else has any suggestians i'd be much abliged for ur help.... can't i jus bust da honey comb out of da catalic, or is dat pointless?

have u dropped the exhaust 2 even look @ the cat yet? b4 u bust up the cat's guts, why not put in a "test pipe". u know, a small stright piece of pipe used to bypass the cat & "test" the truck 2 see if it still "chokes" when it gets warm.

It would be a 4.3 liter V6.

Sounds like your throttle body is partially clogged. Get some throttle body cleaner (spray can)and spray it in there with the engine running. That should make a difference.
