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.

Any ideas?

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?

Which app is that? (as I look for p0172 fixes and get distracted by shiny)

The APP is: OBD FUSION
