The piece of plastic in the distributor where the two different cables plug in is the ICM. While you have the cap off look at the pick up coil. If it is falling apart it needs to be replaced. It requires the removal of the distributor to get it out. When removing the distributor always replace the O-ring or you will have an oil leak.
This is what a good pick up coil looks like.

So icm has already been replaced and I tested it on my own and then took it to O'reillys and it passed their too so not the icm.

That would suggest starving for fuel or a clogged CAT, but it should happen with the engine hot or cold.

It's running super rich though and is burning through gas like crazy, so I don't believe it's getting starved of fuel 🤔

With that bit of information, I would say the Coolant Temp Sensor is not working.

Already replaced it and verified that it's working.

A sensor is sending bad information to the computer. Are there any leaks in the exhaust system? The O2 sensor may be working, but picking up bad information.

No leaks from what I can tell, and I mean it could be faulty o2 sensor I replaced it and it had right readings?

The 2.8 O2 sensor is the single wire type. So it's ground in the exhaust piping its screwed into. The exhaust is bolted to engine. Engine has several ground straps to body and chassis and they like to break over time. Pick up some 1" braided ground straps long enough to connect from engine block to car body and chassis.
Plan "B". Use a cheap $8 multimeter from Harbor Freight and check for resistance Ohms between body of O2 to engine and then to car body. The lower the reading the better.

It worked for me.
