O2 question

[EMK]

What would give me a 1.070v on B2S1 when all the others are running around .795ish? I have been doing nothing but trowing money at this truck and dont need to run right out and buy a sensor if I dont need it.

In the last month I have bought a fuel pump, fuel filter, cap, rotor, plugs, wires, TPS, EGR, and Y-pipe. My pockets are hurting right now.

A very rich right cylinder bank of a very screwed up sensor. How are you getting these reading. the average should be about .45 volts for a ideal mixture. above is rich. below is lean.

anything above .75 or below .25 should be throwing a code at you under most circumstances.
