Stevester, you don't say where you are from. As far as I know the smog requirements are State wide and the certificate doesn't refer to MPH but to RPM's. I just pulled my last test on my '97 CL600 with the following results:
Idle HC (max) 100 (Ave) 17 (Measured) 10
2500 RPM (max) 130 (Ave) 12 (Measured) 11
I don't know where you got your numbers or who Murphy is. My hulking 12 cylinder beast passed with flying colors but I do have new O2 sensors and Magnaflow cats that were installed a year ago. But then the car only has less than 70K. However, this is my 5th Benz and I have never had any smog pass problems with any of them, even those over 200K miles.
