'96 C1500 4.3/4L60E - Misfire after Trans Swap

Mechanic friend of mine says I have it right ^

Will still check the manual when it arrives.

Alright, I can accept I was wrong, but I don't understand why you'd have three pre-cat O2 sensors.

well I guess the value here is since the code is on 2,1 the problem is affecting the odd cylinder bank, so I think that’s ignition or one of the spider injectors

I bought new ACDelco cap, rotor, plugs, and wires to put in this weekend. Was already on my to do list.

The chiltons manual I bought doesn’t have a diagram for a 1996, but here’s the diagram for a 1995 which confirms I’m focusing on the correct sensor unless it changed from 1995 to 1996. 1996 was when OBD2 was introduced.
