SAw your post on cat problems "You can try the anti-fouler trick. Buy 2 spark plug anti-foulers that will thread onto the oxygen sensor. You'll have to drill one out so the sensor will fit into it. Thread both on the sensor and re-install. This pulls the sensor back out of the exhaust stream so it reads less oxygen and will usually solve the 420 code. It costs less than $10 to do, so it's worth a try.

Never heard of these, but I would like to try on my Toyota. Where can you get these?

Thanks
