My 2007 yaris Idles rough when i come to a stop.

2007 toyota yaris 300k miles! Because of the mileage I’m not looking for a miracle here obviously things are worn out. But I’ve been babying this car and it still has the original brakes! Recently I got a check engine light and replaced a couple coils… Number two and number four cylinder. The check engine light went away. I accelerated hard one time and the check engine light came back on. P0 300… P0302P0304. Same codes I was getting before before I changed the coils. The irony is after I did the hard acceleration the car actually started working pretty good. But the check engine light is still on and the engine runs just fine. With one exception. When I pull up to a stoplight after going 40 miles an hour… When the car stops...The engine has a hard time recovering back to idle speed… Just for about one second it runs really rough and then recovers back to idle. This only happens when the engine is in gear… If I started the car and let it idle in neutral it would idle with No misfire and no problems. This car could probably do for a fuel filter change… Obviously because it’s at 300 K… And I have fuel injectors on hand to replace The old ones. Is the transmission affecting my idol that’s why the vehicle has a hard time when it comes to a stop?
