Thanks for all your help guys...means alot.
The red black wire is on the Dr side, I'm on the passenger side...got red, red/white, grey/red and grey/blue.
Jbrew do you think my cats plugged then? Would that cause the voltage to constantly stay pinned at 1.275 on live data?
I'm trying to upload a video I just made of the live data screen on my scanner. I also tried unplugging multipul injectors in different orders to get see if it was one or more injector.

I hope you guys can see that...I can't get it to upload any other way...hate electronics! Lol
I wanted to show that bank 1 s1 constantly shows 1.275 no matter what and b2s2 only switches between .030 and .035...
Thanks guys

Did some more poking around. Fuse 24 in the engine fuse box only has 10.5 volts...rest have 12. I'm pretty sure the 02s are on that fuse, see if I can get to this this weekend

OK so spent the day fixing more wires. Finally got it all back together, fired it up and put the scanner on it. B1s1 02 was showing loooow numbers, .025-.030... Checked voltage at the plug, 5volt reference wire only had .05, key on vehicle off.....any ideas?? And I tried 3 different 02s in that plug, all did the same thing

I replaced the computer, all the oxygen sensors are working correctly now. Truck still has a slight miss though. I did find a rust hole in the egr pipe I missed before, fixed that, pin hole above the pass side cat, fixed that. Havnt driven it since but I started it up and its still got a slight miss to it. I was getting a cylinder 1 misfire code before I fixed the exhaust, hopefully that goes away from the cat being fixed, I also checked the plug for cracks, plug wire and the injectors. My trucks got high kms on it...330000 kms...so don't expect it to run like new I just want it to run better. If I get another misfire code I may replace the injectors, there's a set locally for 150 bucks brand new. I'm also going g to swap coil packs side to side to see if the misfire carries over. Anyway, sorry for the long post and thanks for all the guidance

Has everyone given up on me? Lol
I tested my coil packs today. When testing the secondarys (where the plug wires mount) I got 13 ohms. It supposed to be between 6.5-11.5... My multimeter was set to 20k ohms... Is that the correct setting? I tried just 20 on the dmm and got no resistance on either coil pack. Still learning about electrical...thanks

In case I missed it, what about those shredded wires on the back passenger side? How well are they reconnected and sealed up? Are you sure they aren't pulling out of the source? Those go to the computer
