There is a program called consumer repair assistance through CA/BAR .If he/she wants to participate he/she can ask for the application from the smog check station or print it from their web site(
WWW.smog check.ca.gov).Based upon its report that I see is qualified for $500 free repair money, if the repair bill goes over that amount he/she will pay the difference.As far as the diagnosing the problem goes its most likely due to lean mixture and its clear because the CO&HC have good numbers,the second cause of failure could be the MAF and O2 sensor.Don't let anybody tell you ,that you need to change the catalytic converter,it is in perfect condition based upon the reading that I see and mileage of the car,I have seen porsches with well over 200K miles with original cat that it passed the smog (mine one of them).Good luck.
