help! truck sputters and wont move

[K5Greek]

heading back from the mall bout 1/2 hour ago, i made a turn and was accelerating and once it hit around 25-30 mph the truck started to sputter and wouldnt let me go faster..even after this i cant really go over 25-30 before it sputters and wont move

now im either thinking cat, fuel filter,fuel pump, or i dont know what. is their anyway to distinguish what it is?

25-30 before it sputters and wont move

You mean it won't move as in comes to a stop, or it just keeps moving at 25-30?

Check your fuel pressure with a gauge.

it just has no guts..it sat for about an hour once i got home then i took it out with my bro and once she got warm she started poping and funky smell came. we had to idle it home cause as soon as we gave it a tad bit of throtle it would start poping and died like 3-4 times. so my guess is clogged cathttp://poststuff4.entensity.net/100206/media.php?media=stomp.wmv

I vote for the clogged cat too, if it get worse when it warms up. You could put a vacuum guage on it and see if it pulls less vacuum when it gets warm. Or drill a 1/8 hole in front of and behind the cat. If the pressure feels the same out of both holes, then the cats alright.
