[Just-in-credible]

Well this is interesting…
As you will recall from my last post, I was having issues with the O2 sensors. The tuner guy gave me part number of what I needed to order. With the part number in hand, I went to my local GM dealer. I ordered up the part, and they told me that they would be there in a few days.

SO back I go to the GM dealer a few days later. I ordered two…they only shipped one. No big deal. They had one at a dealer about 45 minutes away. Back in the truck I go, off to the next dealer. I pick up my part, and head back to the shop. I crawl under the truck…unhook the old sensor…FFS…the guy gave me the wrong part number. I had a male square 4 pin, I needed a female square 4 pin. ARGHH!

So this time, I decide to go to amazon for the parts. I order up the correct part numbers. And I wait another week. I pop in the new sensors…fire it up, pull it out of the shop…AND THEN…
