First day on the road .... Not a good day

Buzz - I will check my OBD2 reader and see if it has this data, but I didn't think so. Either way, my ultra gauge will be coming soon and will do the exhaust test and can go from there.

Ultra Guage readings for O2
Planning on starting my head gasket job tomorrow.
While driving to my garage I recorded some footage from my newly acquired Ultra Gauge. Some notes:
1) My rear O2 sensor on bank 1 doesn't move ... seems like its toast as expected.
2) The differences in the front sensors (bank 1 and 2) is substantial. This could be due to the fact that the head gasket is shot on one side and not the other and therefore the engine runs substantially different on each side. Will repost results after the head gasket and valve job.
3) My engine load is 30%+ at idle .... this seems unusual .... Again. will repost after I do the heads ....
4) The relationship between the 2 sensors on bank 2 seems to be working normal to me but again I am no expert.
Anyone else have any comments? Based on my untrained observation I would lean towards putting 2 X O2 sensors on the bank 1 while the heads are off and exhaust is disconnected ... (I ordered two to be ready). Alternatively if my bank 2 is suspect I can put two new ones on both fronts and see how that goes.

As another interest ultra gauge reading - my instant MPG is anywhere between 700 and 2000 MPG!!! (Other than when I am stopped when it is 0 as expected).
And I think the speed data is fine as my MPH readings are fine ... So does this mean the truck thinks its using a lot less fuel than it is? Ironically I am getting about 220 miles to a tank.

Thanks for the reference MPGs ... but my plug wires are brand new - hope the head gasket job and O2 replacements fix the MPG issue or I wont be able to afford to fix this thing even if it runs well and passes emissions!
