it definately wouldn't hurt to do a tune up on the thing.
start with a fuel induction service aka run-rite, lucas, sea foam, run some of that shit through the motor for 15 minutes and see if that helped any. if that didn't help any i'm leaning towards an egr valve sticking, which would produce a vacuum leak. but honestly i bet cleaning the crap out of your intake and putting some new plugs should clear it up. good luck
