Default Engine Code P0172 and P0175

My check engine light is on with these two codes, any suggestions of what the issue may be? It's a 98 s70 T5.

the p0172 is likely a vac leak. Not sure about the other.

Hey Guys.

So yesterday, I change the PCV OIL TRAP VALVE COVER Part No. 31319642 on my 3.2L and cleared/reset the P0171 and P0174 System Too Lean codes and now the engine is smooth and not misfires.

So today I was driving and my check engine light come on and these are the codes I get:
P0172 and P0175 System too Rich.


Any advice what to check? Or what other test to make with the OBD Scanner?

THX,

Isaac

Here is the screen shot of the OBD Codes and also the Term Fuel % on idle on Bank 1 & 2
