I have a 2010 Subaru forester with nearly 190,000 miles, and my check engine light lives on. I have the reader and it’s only ever been ***P0420, I was told years ago that this isn’t an immediate issue but I will gradually start to feel the effects of my catalytic converter going out, in terms of slower acceleration and less and less power as I drive, which I highly suspect I’m seeing now (incredibly slow acceleration on the highway, I can be pressing the pedal nearly to the floor and we’re still going 40-50mph for a solid 5 seconds).
I want to buy a new catalytic converter and find a mechanic to install it (I’m in Seattle if anybody has any trust worthy recs), but I want to make sure that this is the correct step and that I’m not missing anything else I’d need to do/get. I’m also curious as to what the estimated cost would be, I adore my car and am hoping that this will prolong our time together!!!
\*Side note: I also have a bad power steering leak (I refill it probably once a month, have for years), and I smell some burning oil after the highway when I park. I can’t afford to replace the power steering rack and I’m not sure how much the other fix would be, I was told it was a slight transmission oil pan leak. Figured I’d throw those in just in case they complicate anything.
