Ok so my Dad has a check engine light on his 04 Tundra and took it to the Dealer in Havasu. They told him both of his Cats and the bank 1 o2 sensor need to be replaced! 3000.00 bucks! Here is the work order to so you all can see what they said. Keep in mind he drove an hour away from home with no power problems or chugging, like cats do when they are bad. What do you guys think I should start with as far as parts???
