    After installing new O2 sensors, mad, and new aftermarket cats. All was well for about 7500 miles, then that silly code reappeared. The I discovered Underdog Racing Development- installed their sensor (a 2 minute job) and no more P0420:cheers::cheers

    Excited to see if my mileage improves a bit:D

    Thanks for the comment. I read your post about three hours after I placed my order for the same thing/problem on my 2002 3RZ. Let's hope it works as well for me! Pete
