possibly a bad fuel injector. Try some fuel injector cleaner. Add it to the gas.....it can't hurt I would suggest a bottle of Techron, you can get at Walmart or most auto stores. It's the best I have used. It could also be a broken plug wire, a plug wire that may have come off the end of the spark plug, a dirty fuel filter, clogged or dirty air filter, dirty throttle body, a Vacuum line may have come off ....just a few things that may be causing it also.
