Installed O2 sensor. Here is what it changed.

1. Truck has noticeable power increase
2. Miss is still present after truck warmed up
3. OD and TC engaged normally after truck warmed up
4. Miss is definitely present during acceleration and OD engagement
5. Miss is VERY noticeable when OD engages, as Transman and Nitrous both said


The speed sensor should be here in a couple of days, and I will install and report back then.

Truck is driveable, operation is better, miss is still present. At one point the miss was hard enough that it felt like the truck wanted to backfire. This was accelerating from a dead stop at a stoplight.
