My indy is pretty sure it is. I had him clear the code last Friday and he said it's most likely the cat if it came on again. He says he usually stocks three cats at any given time since it happens more than you'd think. It came on again a couple days after he cleared it and hasn't gone away all week. I had the plugs replaced a few weeks before the code, but I haven't noticed any misfires or issues that would indicate a bad plug. The dealer's going to do tests to make sure the cat's bad anyway, and if it is bad it's not my dime anyway.
Adam - I did see that 126. I think it's been there a while. You saying I should dump the Subaru and pick up another Benz?
