The code showed up on the bottom left corner of the instrument cluster when I set the key on accessories and held the "A" button in.

You will needs an OBD2 scanner to scan it the vehicle's computer. I will opt out and another tech will help you out?

After you scan the vehicle, you should get a P0301 through P0305 if it is a misfire code, and 301 is for cylinder 1 and 305 is for cylinder 5 etc. If you can tell us the exact code we can help you pinpoint it. Let us know what you find there and write a list of all the codes stored in order they appear.
