Car throwing P0420 code and oil pressure above normal
Yesterday morning the SES light came on so I took it to AutoZone to have them scan it and it was reading code P0420 (Catalyst efficiency low - bank 1). I've also noticed that the Oil Pressure gauge is showing a significant rise in oil pressure (normally it sits at around 45, now it sits around 55-60 or more if past 2/3 throttle). Off the top of my head I'm thinking maybe a bad PCV valve (would explain the increase in oil pressure),but I thought I would post and see if anyone else has experienced this and what the cause was in their case.
Any ideas?

I called the dealership today and apparently my car is still covered (my car is a 2000 so I guess that it includes the 10th year) so I will be taking it up there tomorrow to have them take a look at it.
