My 1998 Lexus LS400 has been throwing a P0420 code for the last few months. I used my BlueDriver and verify and erase. Car runs fine with 290K on it. Suddenly I had an epiphany! Why not pour some Schaeffer Neutra into the gas tank and see
if it would make any difference. I did and have driven 3 days and 240 miles and no more CEL. Normally it would come back on after and hour or so driving. Very interesting.
Now it may come back tomorrow but Trav has helped me get a back up plan for less than $10. Please don't fuss at me Trav. had to get a SS one. LOL
