You can get a throtle body cleaner for that purpose although carb cleaner works fine too. Start the engine, un-plug the the pipe comming in fron the air filter, you should be able to see the fly. It opens as you rev the engine. spray the throtle body cleaner while reving high. Dont use up all of the cleaner at one time, depends on how much carbon deposits you see in the throtle body. Even when you are done spraying keep reving the engine for like 30 secs or so to make sure everything that went in is burnt. You will feel a funny smell comming from the exhaust tip and probably carbon deposits too. Cars throtle response should improve after this little trick. Enjoy the ride and be safe
