The first three are the important ones. Generally If you have high NOX you are running lean and the combustion temp is very high (1600 degrees give or take). The higher the temp the more Nox. HC and CO should be low.You may have an intake manifold leak somewhere after the Mass-air flow meter the computer cannot see. As for you're cat being defective, if the truck is OBDII the computer will measure it's efficiency with numbers from both the upstream O2 sensors and downstream sensors. If the numbers are similar you will set a code and the check engine light will turn on and probably flash. Check for manifold leaks first (EGR, hoses, PCV, cracks) and anything else connected to the intake system. Start there and see if you find anything. The smog guys should have told you this stuff after the test was failed. <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
