Well, I bought a 2002 Rav4 last thursday, it had 36,700 miles on it. I managed to get it back from my wife today and noticed the CEL on. Between school and work tonight I stopped and had the codes checked at autozone. They were busy and I was in a hurry but was told the cat converter is bad, bank 1 and bank 2. He cleared the light before I could tell him to leave it on. I have read all about the cat problems on this forum tonight. Now I just hope the dealer will make it good, or I won't be keeping this one very long!
