02 maxima running sluggish

Just got an 02 maxima and I’m having problems accelerating after car is in running temperature. Takes off no problem when it’s cold. The moment it warms up it’s just very sluggish, only code I’m getting it’s p0420.
ive changed plugs coils and firewall side converter. Any help will b appreciated

Just a suggestion to maybe change the 02 sensors on both banks.
