2005 Altima misfiring problems?
AutoZone diagnostic said misfiring on cylinder 3, we got recommended coil pack for cylinder 3 and all new recommended spark plugs.
3 is still misfiring. Any ideas?
P.S. Sorry for not having been more specific. We did already put in the coil pack and plugs. It's as if they didn't do anything at all.

First step is a compression test, if that's OK then a careful check for a vacuum leak at the #3 intake runner, then try swapping injectors with another hole and see if the misfire moves.

Replace plugs and coil pack. It could be other issues but plugs and coil pack are usually the issue. It's cheap enough.

Check the injector, and the cylinder compression (you may have a leaking valve). Good luck.

Either keep throwing parts at it and crossing your fingers or go to the dealer.

Sounds like the issue is that you have a misfiring on cylinder 3.
