by putting on a new gas cap. just thought i would pass that on. cel went on while driving normally. my scan tool suggested an oxygen sensor was bad. my wife said "it's the gas cap" [based on an earlier experience with her es300]. i bought a new gas cap at auto zone [$7.50]. problem solved. i wish they would all be so easy.
