2001 RX300, 80k miles. Getting error code "catylyst efficiency below threshold bank. I'm having a hard time believing the cats are bad at this mileage. Thinking about replaceing the rearmost A/F sensor, and then perhaps the others if that doesn't work(?) Comments please? I notice several brands are available. Any thoughts on the brands? First post to the forum. TIA
