Phone slowing down and crashing after root.

I am using a Samsung Galaxy S4 (SGH-M919V), I rooted using Kingo root and my carrier is Freedom Mobile (previously Wind Mobile). Basically, this started about 30 - 45 mins ago. I was messing around with the freedom app and I decided to download Temple Run 2. Keep in mind that I used root checker about an hour or two ago to see if everything was working properly and it was. So after I install Temple Run 2, I use freedom to test if it works, and it did. So I mess around a little more. After about 5 minutes, I uninstall Temple Run 2. Now, my phone is lagging a little more than usual, I cleared the ram but it persisted. So, I just let it sit and it ends up rebooting. I leave it like this and it reboots a couple more times before I take the battery out and let it sit for like two or three minutes. I turn it back on and the problem persists. I end up using root checker again and it says I'm not properly rooted and when I try to open the Kingo Superuser app it closes right after I open it. I want to see if I can fix this without resetting my phone/flashing a new rom. Especially flashing a new rom because I feel like I'm gonna mess up somewhere and break my phone even more.

EDIT: I fixed it by wiping the cache partition and reinstalling Kingo Superuser.
