Alright, got the injector swapped, runs on all 8 cylinders. Buuuut, now i believe the LH cat is clogged. As its temp was 600+ and the other was sub 300 degrees.

I have no squalls cutting the cats off completely, but will this ruin my fuel mileage?

Excellent. Nope I don't have any and am getting @15-18mpg. 3.9 won't get that
mileage because it's not SFI. It probably will reduce back pressure some but I don't think it effects the motor long term. I've had em off for over 4 years now, no issues with exhaust valves.

Just realized that the 95 only has the pre cat O2 sensors, that should mean you are correct and it shouldnt hurt anything. So theres another job on the list for tomorrow.

Even if you have post cat O2's like I do removing the cats would have zero effect on MPG.

I was speaking in terms of burning exhaust valves in regards to back pressure but yes your all set to yank the O2's off without tripping the CEL.

Spike, that is what I was implying, no effect on mileage.

Alright, she seems to be running decently now. Knocked out that bad cat for now. Found a bad spark plug (they are brand new) was shorting out somehow and preventing a cylinder from firing. Other than that it seems 6 BTDC isnt right for this truck, she wasnt running right timed like that.

Not much power on the low end and it seems to stumble until it gets into higher rpms. But, i might mess with the timing tomorrow and see what changes.

Cleared the ABS codes, didnt see anything wrong with the ABS system other than the fuse was pulled and was showing codes for the right rear. Didnt see anything bad back there, only time will tell.

Replaced a bunch of bulbs and found out i wasnt a fan of their socket design.

So to anyone looking at this thread trying to diagnose your own problems, this is what fixed it.

Ignition Amplifier ( I replaced it with a GM Module)
Dizzy Rotor
Fuel Injector
Bad Plug
Clogged Cat

The only other issues im having is the SRS light is on, and a few other little things
