2000 accent engine hesitation

Hi everybody. So, my poor accent started to have some kind of engine hesitation when accelerating. It idles perfectly fine and can rev up normaly if I push the accelerator realy slowly but it is not drivable that way, it wants to stall when starting to move form standing still or after a gear chnge at lower rpms. The problem begins when I want to accelerate faster which is nececary when starting to move, if I rev a bit harder while I am parked the engine will stutter for a seccond than it will push throug and rev normaly after about 2500 rpm. This is how it began. My clock buttons dont work so i disconectet the battery and wanted to reconect it at 1 pm which is the time my clock resets to but after reconecting the battery this hesitation started to happen. It is not the first time but before it would go away when the engine would get to operating temperature and after a short drive but this time it keeps hesitating. I expected it to go away as usual but it wont so here i am asking if anyone had a similar problem how did you solve it and what went wrong. I am not getting a check engine light but i dont have acces to diagnostic at home and the coronavirus bs closed the mechnic shops in the area so i can't go there. Hopefuly i managed to explain what is happening and someone will be able to help me. Thanks in advance. Chears!
