You have to localize the noise. Maybe there are pebbles under the pedal or carpeting bunching up. See if you can find out where it's clicking. Maybe you should try to operate the throttle by hand at the engine and see if the throttle itself is sticking. That can happen from carbon accumulation which can be cleaned. Also, your throttle cable may be wearing out or getting full of dirt. check it out and get back.
