When the car reaches the operational temperature the rpms goes below 500 during stops at the red light. I brought car to autozone and no codes are detected by the scanner except for something about evaporation.

That may be the evap system so it needs to be smoke checked by a pro to see wher eit is leaking. Try cleaning throttle plate on both sides with choke cleaner as well as iac hole.
