stumbling idle, HELP

Alright everyone I know I haven't been around in a while but I've been busy,
I come here to you guy's with a problem thats got me a little stumped.
I have an 89 full size bronco 4+4 with a straight 300 fuel injected (6 cylinder) that ran perfectly smooth just 3 day's ago, today I started it and at idle it sounds like its running on 3 cylinders struggling to stay alive, but when I give it some gas it smooths out until the rpm comes down and then it's rough again. I've been having a problem with one of my neighbors and I'm worried that they may have put sugar in the gas tank, does anyone have any idea what the symptoms of putting sugar in the gas tank are, or any idea as to what could cause this problem that I have.
This truck ran great just a few day's ago.
Thanks my fellow Hot Rodders, I know this truck isn't a Rod but this is the place that I like to come to when I have a car problem, usually my problems have something to do with a 50 year old truck and not my daily driver.
Thanks, Devin
