^^^^^^^ Exactly the guy failed in HC and Co @ idle!!!!!Why in the hell are people telling him to clean his EGR? High NOX readings are signs of bad EGR system ,period!EGR does not open @ idle !It only opens @ off idle and cruise not @ idle!!!! therefore stop telling the guy to clean his EGR.He failed @ idle people. !

Some of you sound like you know what your talking about but in reality dont know anything , look at his results Study them before you assume its an EGR problem! So much misinformation.
