I posted a day or two ago that my SM O2's were dropping to 000mV under WOT. Cross counts weren't budging, and were basically locked on a number.
A few people suggested it was the O2 sensor. Sure enough, I picked up a new Delco O2 at Straub Buick today (ya' know, the dealer with a 400-mile GNX #119 sitting on the showroom floor) and dropped it in tonight. Problem solved.
The Tomco sensor only had about 500-600 miles on it...no leaded gas, only some Sunoco GT100 unleaded.
Just thought I pass it along as an FYI.
