First thing I would do is change that 02 sensor.  Even if it's not the
problem it will pay for itself in increased gas mileage.

Hi All-

Took the S6 for emissions testing in RI today and failed!  Passed the CO
portion of the test, but failed the HC ppm both at idle and 2500rpm.
Limits are 220 for both and my results were 266 and 245 repectively.  Is
the HC indicative of running rich?  Or is this a faulty 02 sensor fault?
Is this due to the MTM chip?  Anyone know of a fix?
