could simple as fuel filter(rec. change every 20,000 miles). could be build up in fuel system or exhaust system. try ethanol treatment to 1 tank premium to clean fuel system. ethanol blend in today's fuel causes a lot of build up that can inhibit fuel delivery as well as increased wear on spark plugs. review when last tuned.
may want to consider upgrading from conventional air filter to a high air flow filter(K&N).
