I used to get the code about every 15k miles, but now I'm getting it every couple of weeks. I don't have the readout right in front of me, but I think it's a code 0430: catalyst efficiency out of spec in bank 2. Is this a known weak sensor or do I have a cat. going out?
I previously thought it was happening whenever I used Amoco gas, but now it's happening with others. Could fuel be an issue here, or is it just coincidence?
I'm due for an oil change in about 2 weeks, and I will have the dealer look at it then. I'd just like to be prepared if they're going to tell me my ride is hosed.
