You mentioned CAT cleaning? What's your preferred method? Is it just a temporary fix?
Sent from my twisted mind of the mudman
Temporary fix Tim. I used a bottle of CataClean as directed and it solved the problem temporarily. Experience has taught me that once you get a P0430 or P0420, the specific Cat (left or right bank) is on its last legs. You can keep cleaning it, but eventually the code returns and it will need to be replaced in the very near future. Better to just replace it, along with the upper and lower sensors.
