My car once in a while idle rough when stop at light, also when the car is park I accelerate to 3 to 4 k rpm when I let go of accelerator Padel the RPM drops below idle Momentairly. No engine lights come on.
It has shut down twice. So far no warning or any lights.
1. Is it Idle air control circuit valve /
2. Or map sensor?
3. Can they be cleaned?
Please let me know
have the same problem?

Yes, it most probably is a dirty IAC and throttle body. Get them cleaned with carb cleaner and the low idling should be resolved.
