So I’m currently having an issue with my 2008 Honda civic SI where when I start the car on a cold start it runs fine and then shortly after a couple of minutes, the rpm’s start to reach at 2k and the car starts revving on its own and bouncing up and down to 1.5k to 2.k rpm’s, I was told by the previous owner that all I’d have to do is change the current gas pedal to another that he gave me and it would resolve the issue and I also have a check engine light because of this.

Never believe anything a seller tells you. If it were that simple the previous owner could have done it, sold the car without that problem probably for a bit more money. Did you have a mechanic check the car out before you bought it?
I also have a check engine light because of this.
That means there is at least one code stored. What is it?
@chucktobias I mean the car is pretty clean for the most part, I bought for 4000 dollars with 82996 miles, all the car has is this current problem with that and I have a spare gas pedal to change it and I’ll see if the problem goes away I was just wondering if doesn’t work what other possible problem can cause this? And I’m also not sure what code it is for the engine light.

It's not a good idea to buy a used car without a mechanic checking it out. Plenty of clean-looking cars wind up hiding serious defects not disclosed by the seller. After all, that thing is 17 years old which is plenty of time for things to go horribly wrong. (Although possible the low mileage is suspicious - that's less that 5000 miles per year.)

Since that car has an electronic throttle body replacing the gas pedal assembly might help if the pedal sensor is bad.
If the problem persists you need to know what code or codes are stored to get an initial idea of what's going on. (You really can't work on a modern car without a scan tool. It doesn't have to be an expensive one.) You could also try cleaning the throttle body and MAF sensor since that's easy enough.
@chucktobias Yeah I did find it a little odd for the price and miles, but I’ll see what happens and if it continues I’ll consider cleaning the Throttle Body or the MAF sensor, thanks for the advice!
