2005 GC engine codes

I am getting P0300 & 0301 (cylinder misfire) engine codes for over a year with the engine light over this time. Dealer has no clue and wanted to "tear the engine down" to fix it. Ah, no... Could it be a blocked catalytic converter? I have +160k and have no intension of upgrading.

Any comments would be appreciated!
