I converted my fusible links to Maxifuses thinking it would solve my problem but not really. When I applied the gas pedal the car would choke really bad until I let off my foot. It's not all the time but recently it's 90% of the time and it seems like it only happen after 5 mins or so after warming up. I'm thinking fuel filter or something with fuel system. I've changed spark plugs, distributor cap and rotor, and have Taylor's 8mm wires. I also plan to pour some rubbing alcohol into the gas tank to see get rid any water. Do you pour in the entire bottle or just a little? Any other advice would be appreciated greatly.

I don't suggest alcohol in the gas, if you feel moisture is an issue you can buy fuel system dryer for a few bucks and it's got instructions, but sounds like your problem is the CHTS, which looks like an injector connector and is located on the front lower portion of your thermostat housing, make sure it's plugged in and that the contacts aren't all corroded, could be a bad sensor but most often it's a commector problem

I changed the fuel filter and man it was disgusting, brown fluid be coming out. The car became better but only for less than an hour. I decided to WOT it to see how it would respond then choked a lot until I pulled over and shut it off. It's weird cuz it would be ok again after I turned the engine off for few mins. What is CHTS?

Cylinder Head Temperture Sensor, basically it tells the ECU that the engine is cold so it sends extra fuel, but if the engine is warm and not in need of the extra enrichment it can fuel foul the plugs, a bad or disconnected sender basically makes you dump extra fuel in, not noticable when cold as it's needed at that point but once warmed up you get a flood situation
