How do you remove the coil pack on a 2017 Elantra 2.0L. Mine will not come out after removing the bolt holding it in place.

What is your question?

Check engine light on with P0303. 3rd cylinder misfire. Looked at manual, says replace spark plugs at 45k miles. I have 44,500 miles. Still under warranty but did not get a warm fuzzy about taking it in after talking to dealership in Stockton CA. So I figured I'd change the spark plugs first then take it in if CEL does not go off. Got new plugs, removed cover, removed bolt on coil pack wiggled and slight twisting to pull off --- no way was it coming off - sure enough, pulled coil pack off assembly but not the part that has the boot over spark plug. Same for cylinder two, except the coil pack assembly came apart at a different place with boot still on spark plug. Good news, I re-assembled both coil packs, bolted it in place and it still runs, cleared CEL, ran good for 50 miles CEL back on. How do you remove the coil pack in one piece so that you can get the spark plug out?

What makes this problem better or worse?

CEL after engine is hot
