The acceleration sticks is it a cord or is its wireless

Make sure floor mat is not compromising accelerator pedal operation. Check throttle cable for sticking and binding.... lube if necessary. Check throttle linkage at intake for sticking/binding and repair as necessary

Wild guess the Throttle cable is frayed and "sticking" in it's enclosure. or if you are lucky it needs lubrication. Or possible the throttle mechanism itself needs some attention. Live in a "salt" area? Corrosion causes a lot of bad "behavior".

WD 40 all over what you can see inside then from the under side as well. probably has build up on it ,just needs cleaned and loosend up.i had one stick on me one time because of it .

Could be dirt or varnish inside the throttle body. Could also be a sticking idle air control valve.
Is the check engine light on ?

Replace the accelerator cable since it is worn and sticking. It will loosen up as you say altough someday it will jamb up while your driving it which will be a dissater in most cases

Two major reasons for this are dirty throttle body bore (clean with carb cleaner) and frayed throttle cable (replace cable)

If the engine is surgeing without accelerator sticking then you have an idle air solenoid valve sticking. Sometimes they can be cleaned and put back in and work fine and then sometimes need replaced. Clean with carburator cleaner. Be careful when removing it from engine intake to not damage it's seal.

Possible throttle cable, diconnect from throttle body and move back and forth, should be very easy to slide inside cable

Take off the throttle body (very easy to do) and use carb cleaner to clean off the gunk. You have to clean both sides of the butterfly.

check your airflow meter air hose
