Couple questions on 2000 silverado 5.3

[trapperman83]

First off my ABS light only comes on after I reach about 5 mph, I'm wandering if it's the speed sensor?

 

Then i notice a slight miss sometimes when at an idle, my bank 1 sensor 2 shows low voltage gonna replace that this weekend but would that cause a miss? It has brand new napa plug wires and brand new iridium plugs, just nit sure about the miss, I checked the intake gaskets with the carb cleaner trick, nothing there, any help would be great thanks.

For the ABS light, get it scanned or you will just be throwing money in the dark. As for the O2 sensor, I would recommend replacing them in pairs, as they do not read as well with age and that can cause differences between banks.
