it was behinde the muffler. i switch from a single to a duel about 7 years ago. the quick fix i made and it worked for about a week or 2. then i left for work. the truck ran fine for about a mile or so then when i made a uturn i hit a good sized bump that jurked the truck a great deal. after that i hit the gas pretty hard and thats when it started to happen. now when i start it it runs fine untill it gets to indle and then the truck runs ruff.

Happened to me once when my positive battery connection came loose, or when my battery was going out. Not sure why the alternator didn't take over...
Or maybe a fuel deal.

Sounds like a vacuum leak like cincyfx4 said. Especially if she won't idle. Double check all your rubber hoses, and listen for vac leaks. It could be your idle air control motor is gummed up, worth cleaning if you don't find bad hoses.
