So I started my car and after 4 years and 40k miles of trouble free driving I finally got the dreaded light. I looked up the codes and got 3 way cat right bank, rear heated 02 sensor, and knock sensor. How hard would it be to fix these myself? I'm not mechanically inclined but I can do basic stuff like intake and change my oil. Also does anyone know what I could expect to pay at a dealership? Unfortunately I am away at school right now so I have very limited access to tools and don't have a real place to work on the car. Also, don't know if this has anythign to do with it, but the night before I drove for 5 hours in a snowstorm which no cel and then the next morning I got the light as soon as I started the engine. Car seems to be running fine(normal mpg, good pull, etc)

The knock and o2 can be done easily. Knock can get frustrating, but do a search and learn the creative methods members have used. give yourself 1hr for that (should take a few min if you kno what you're doin).

O2 is a cinch 5min job. It does require you to get under the car (right behind the cat converter). When you buy the sensor, ask to borrow their o2 sensor socket. Otherwise, use a wrench.

fix those 2 first, then see if the 3way cat comes back. Check prices of knock and o2 on autozone.com or something. Oh yeah, autozone.com will tell you how to change those parts (i think).
