Rps sticking and jumping after running dry of oil

For the last 2 weeks, my rpms were sticking and jumping, my car was over heating and I had a coolant leak. This weekend, I ran my engine completly dry of oil, it died, and I replenished the oil and it died again. I then changed the oil filter and my car ran perfect, better than before.
it ran perfectly for monday and tuesday.
today, my rpms have started to "stick" again, meaning, when I stop accelerating, or the car has gotten up to speed, the rpms do not lower. As well, they are riding very high, ex normal doing 40km would be 1.5-2, now is running 2.5-3.
as well, when I am slowing down and go below 40, or start to come to a stop, the engine sort of "jumps" and the rpms sort of jump and lower.

im terrified it will break down again.
before every drive I have checked the oil and coolant and both are full.

any suggestions would be so greatly appreciated.
thanks

What was the coolant leak?

You have damaged the motor by running out of water and oil. You need a shop to do a leak down test and oil pressure test to see the extent of the damage

After it broke down, and I put the oil in and it broke down again, is when I took it to a mechanic who changed the oil again and filter and did a bunch of tefor leaks and said there was no, and that I was very lucky and no damage was done. They were shocked that even though it started smoking, no lights came on and the temp didnt rise until right as it shut off.

But they said there was no leaks and no damage, and everything was better than before I bought the car until today.
