HPT - No signal from O2's. Total newbie to tuning. Car is a 1998 Z28 M6 with longtubes, no cats/rear O2's. When scanning the vehicle, the O2B1S1 and O2B2S1 do not show any values. The car runs fine, but gets horrific gas mileage, I've never had a tank go over 300 miles (15.5gal). No SES codes for either oxygen sensor, although one is spliced and extended from the previous owner's header install. Any help is appreciated.

Even a failed or missing sensor should show
-some- value.
The sensor PIDs, they are on the table-view
list, right? You might try dropping them and
then re-selecting from the list of validated
PIDs.
