Rough idle, using more gas, poor acceleration?

I noticed my engine was a little louder and shaking a bit more than usual, using a little more gas, and the acceleration became worse. I didn’t get a check engine light for about 3 days after noticing these issues. But I did some extensive research online and decided to replace all of my spark plugs. That didn’t fix the issue, so I went to AutoZone to get a code reading to find out what exactly was wrong with my car. The reading specified that I was getting a misfire in cylinder 2 and 3. So I switched the ignition coils around and waited for my check engine light to come back on and got another reading. If it were the ignition coils, the reading should’ve said that the misfires were in cylinder 1 and 4, but it still specified that the 2nd and 3rd cylinders were misfiring. At this point I don’t know what else could be wrong besides the wires on the ignition coils.
