Mine was doing something similar, except it idled poorly as well. Check your plugs & wires. That was what was wrong with mine...I had melted a wire on the block.

Just give yourself a general tune-up and change the spark plugs, mine was missing alot too. I just used some fuel injector cleaner, carborator cleaner and 6 new spark plugs and shes running great now.
