Hi All-

Took the S6 for emissions testing in RI today and failed!  Passed the CO po=
rtion 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 in=
dicative of running rich?  Or is this a faulty 02 sensor fault?  Is this du=
e to the MTM chip?  Anyone know of a fix?
