My guesstimate on where the wideband sensor needs to go was spot on. Tons of room above the driveshaft.

I also found a probable cause to my exhaust leak and pissed off O2 readings. I dropped and didn't install the metal donut gasket to the manifold on the driver's side. Oops.

So I tried quality ac Delco rotors and pads. They made it a little over a year before getting warped.

This time im trying raybestos rotors and Bosch ceramic pads. I hope they last longer.

Turns out the upstream sensor I installed was from my old gmt800 Yukon. Not compatible. CEL thrown.

95F and %100 humidity today, but fixed. Ick, those welds!
