i have a problem, my father in-law car a 2000 es300 STOCK is not running right.

here is whats going on.

the car idle high around 2ooo rpm or close to it.
when driving the car the car feel like the car is not getting enough gas or something bc its feel like dying when stepping on the gas.
the light dims back and fourth
very bad gas mileages
the headers turn bright red when leaving it on more then 5 mins
even when a cold start and you just turn it on for like 1 min and the headers get REALLY HOT cant even touch it. where i can touch the motor.
i smell gas
smoke from the muffler doesn't feel like a nice even flow. when i felt the smoke the smoke hit my hand like ( exp clapping your hands not a nice flow.) hopefully you guys understand that.
OBD2 reader reads multiple misfire FOR GOT the code bc i re set the code and i forgot to write it down.

what i done to the car already.

change the spark plugs all 6
change the coil pack all 6
check the cat and looks clean and clear can still see the honey cone
no fuel leak that i know of

- what i might need to change next
change the 3 spark pluge sensor look alike i know one of them is the o2 sensor. 2 on header and one in the back towards the muffler.
fuel filter
and fuel pump.

First off I wouldn't continue throwing parts at it. Secondly it sounds like there are multiple problems. First I would try to resolve the misfire problem. Figure out your code and it will tell you which cylinder is missing. Unplug the fuel injector to that cylinder while the engine is running and see if it changes. If not you need to do a compression test or leak down test and see if the combustion chamber is sealing properly. If code p0300 is present (multiple cylinder misfire) then things like fuel filter, oxygen sensors, and air fuel ratio sensors will apply. If you have specific cylinder misfires then it will be something only involving that cylinder.
