1998 Subaru Outback All Wheel Drive Automatic 152500 miles
Hey there -
So my check engine light came on about a week ago so I hooked it up to my diagnostic scanner and the code " P0420 Catalyst System Efficiency Below Threshold (Bank 1)" popped up. It's just confusing because with every code, there could be are multiple possiblities of what the problem should be. I was wondering if you might be able to help me narrow down my search. I just bought this 1998 Subaru Outback about a month ago, and it has been driving a little bumpy and shudders occasionally (usually when it's shifting from 1st or 2nd gear). Any suggestions?
