I'll take care of the abs issue once I get this thing running correctly. This misfire has me confused as hell right now

Never replaced wheel bearings. Truck has 86k on it right now. It's definitely misfiring and its more noticible at low rpms.

I should also mention the voltage gauge will show a little over 14 when cold then drop down to a little below 14. I have my radar hard wired into a fuse and when this voltage drop occurs, my radar turns off and says low power.

Looking for help with my truck, it has a 4.3 and has had a misfire since I got it. I've replaced distributor with ac delco, oem crank sensor, coil, plugs, wires, ignition control module, and coolant sensor. The truck is throwing a p0300 p0303 and p1381 code currently. The p1381 code envolves no communication with brake module which I suspect is from me pulling abs fuse due to an abs sensor malfunctioning and locking up the left side when braking. I have a hard time believing the misfire is due to that abs fuse though. Any idea on what I should check next? Compression showed 145 on all 6 cyl, all new Injectors which are bostech remans. Fuel pressure was healthy as well.
