Sounds like you may have a problem with the purge solenoid in your EVAP system. https://www.youtube.com/watch?v=o_kxHJkzF-I

Do you get any other codes other than the multiple misfire? It still could be the purge solenoid. Try putting in a can of SeaFoam in the fuel see if that helps first.

It could be multiple things. you need an oscilloscope to see what your vehicle is doing. I came across an issue with a vehicle having random misfires and it was out of timing
