Question on ecu

I have recently experienced some odd rpms when idle, stopped at a light, or when going in reverse and after starting the car.
When stopped at a light sometimes the rpms either go up to 16000-20000, or the car feels like it is going to stall. When going in reverse the car feels like it is going to stall, when idle and then accelerating, the car feels very sluggish.

Do you have a check engine light?

Check the fuel pressure, idle air control,EGR valve,and throttle position sensor
