Hey all. My '99 es300 failed California emissions test with the following results:
%CO2 %O2 HC CO% NO(PPM)
15mph 15.2 0 91 1.07 12
25mph 15.3 0 117 1.43 28
I had it looked at by the dealer and they wanted $2000 to replace the catalytic converter and pcv valve.
I then brought it to another mechanic and he doesn't think it could be the converter b/c of the sensor ratings before and after the converter. He has guessed that the fuel mixture sensors are bad and need to be replaced. Any ideas??
