Wont Rev past 4k, sluggish acceleration and P2096 Code

Hello

 

My 2006 Legacy Gt will not rev past 4000 rpm it also has almost no power and very poor acceleration and is throwing the P2096 code. I had a VF-52 pun in a few weeks ago as well as tune the code came up before the tune. Could it be one of the O2 sensors or a clogged cat?

Wanted add that my gas consumption has gotten very high since the rev problem started.

The P2096 code is Post catalyst fuel trim system too lean, this is linked to the o2 sensor after the cat so I think you might be on the right path with the clogged cat. Bump

Thank you Jveers. I have read that a clogged cat can cause the acceleration and power problems that I am experiencing so it makes sense. I'm going to have a buddy do a pressure test.

 

If it is the cat are there any after market ones that would be an OEM replacement?

Check if your wastegate moves freely, I had very similar symptoms minus the code when mine got stuck open

It sounds like it opens and closes, but I will check. How does one check btw?

If it opens you should be fine. You should just be able to pull it with some force to make sure it's moving freely. Also a quick rev up may build enough boost to make the wastegate open briefly.
