Now there is no check engine light.
(before changing coils and injectors i was getting misfire in multiple cylinders)

The car will only seem to hesitate when the car is already warmed up. When i wake up to go to work its fine with no issues. just as when i leave work, no issues. The only time the car seems to hesitate is when the car is fully warmed up and i turn it off for 15-20min and try to start it up again or if i leave the car in Park and let it idle for 10-20mins.

When i let it idle it seems fine until i feel it start to shake. I give it some gas and it hesitates no matter what rpm. When i leave it alone for 20min and return, it hesitates right away and eventually shuts off

The only way to make it go away is if i can quickly get it into drive before it shuts off and move about 20 Feet or so then it dissapears and the hesitation goes away.

Parts that have already been changed all from Acura parts dealer

-6 Coil packs
-6 spark plugs
-6 fuel injectors
-egr valve

- i did the acura alternative i dont know the name but it is the intake manifold cleaner along with the fuel injection treatment. and i also manually removed the intake manifold and cleaned all ports.

What could possibly cause this to occur only when the car is warmed up and not cold?

I have read ECU possibly? but would it make sense only when the car is already warmed up??

Check map sensor voltage. if it higher then .98volts. You need valve adjustment.
What the mileage?

sounds like a bad fuel regulator. Very prone to hot start ups also check the data list and see what's going their.
What happens is the fuel regulator does not drop and bleeds back into the fuel rail and load the cylinders and will cause a miss fire until it clears out and may even miss for a few seconds untill it burns. The new updated regulators will have a black paint mark on the top of it. If you don't have that then be looking to replace it. Pretty common when after a hot soak due to engine heat
