@Shadowridr1 Very glad to hear that you found and fixed that problem! Your videos show a much better overall situation. Even the fuel injector pulse widths seem to be more normal at idle now.
Hopefully now you can start dealing with the less-critical issues. For example, I see from your Mode $06 video that all 3 of the O2 sensors still show no current. (We discussed that in your original thread.) I
really think that you need to go back and re-check
fuse #41 in the under-hood box! I'd pull it out and check the fuse's resistance with a meter then check the slot for corrosion (etc). I simply cannot see a different reason for
all 3 of your otherwise-working-fine O2 sensors to be failing the heater current test.
As for the rear axle ("wheel") speed sensor (WSS), I think you may be forgetting about
this post.
In other words, the reported "VSS" values are probably coming from the "OSS" (transmission, Output Shaft Speed) sensor, not from the rear axle speed sensor. If so, I don't suspect that DTC P0500 will be cured by changing that rear axle sensor.
