Auger out the stool with a closet auger.Check the water level in the tank.Also clean out the “holes” under the rim of the bowl.The flapper also could be droping too fast,it might need to be adjusted.Good luck and let us know.You might want to check the flush valve,thats the part that the flapper seats on,to make sure there isn’t something stuck in it.
