Hello i have a 2012 WRX Premium with 80k miles recently i had a check engine light come one. When i put it on the scanner it came up with P0172 so i cleared code and bought up and down stream o2 Sensor. I installed Down Stream o2 sensor and when i went to install upstream it was the wrong...
So my 2010 wrx is in shop right now getting turbo Inlit replaced replaced... can that cause a catalytic threshold to come up... once I replace the hose will it go away? Or is it done for in the cat or sensor ???
