To send it or not to send it, that is the question.
So i just recently got my ranger running once again and ive been driving it a bit to see what i have to fix next and it has been misfiring when the engine is ar operating temp, ive replaced the coil, distributor, distributor cap, plugs, plug wires, timing belt, and headgasket in the past 3 months. Im unsure how to describe it so i just recorded it instead

There is no exhaust actually, I have to figure out how im going to put a muffler on it that makes it quieter but is still hidden underneath the cab.

Well that'd be your problem, or at least it's not helping and making the real problem unidentifiable. Is it carb or EFI?

I'm with dirtman. With the o2 sensor exposed to outside air the computer will screw up air/fuel ratios. Perhaps there is a crack or loose fitting coupler that is letting in fresh air above or close to the o2.

Its located at the end of the exhaust manifold, and it has about 1ft of exhaust piping after it
