1995 850 Codes 4-4-3 and 4-3-5 850 1995

Hi,

I have a 1995 Volvo 850 Turbo 2.3L. Recently it has started stalling and it's getting worse!!! I checked the codes today from the A2 socket and got codes 4-4-3 (catalytic converter efficiency low) and 4-3-5 (slow front 02 sensor). Do I need a new CAT and 02 sensor? Also, I got a new CAT 2 years ago and I thought it would last much longer. I had it done at Meineke. Anyone know the warranty on a CAT? Thanks for any info!! I appreciate it!!
