Rough idle

Topic starter

Good day to you, my wife has a 2017 Toyota Corolla LE with 78000 miles automatic transmission. 

It has a rough idle, when you drive it and come to complete stop. It will start off at 800, then go down to 600. When it does that, it feels like the car is gonna shut off. 

I have clean the mass air flow intake sensor, clean the throttle body and also clean the spark plugs. Purchase the original from the dealership. The problem went away for about six months and now it's back again. 

What else would you recommend me to do to fix this problem?

Thank you
