2011 Altima 2.5 Nearly stalls when coming to stop

Hello,

I have a 2011 Nissan Altima 2.5 SL that has developed a near stall situation when making abrupt stops or sometimes when coming to a stop normally. The RPM’s will drop to 500 or slightly below and then it catches it’s self and idles back up to normal to prevent stalling. Also sometimes the idle will drop below normal when qll ready at a stop with headlights on and/or turn signal on. I have about 59,000 miles on my Altima, the oil is changed with full synthetic every 4,000 miles and has a newer air filter. The battery was replaced a couple months ago and the charging system was tested and all checked out good. I did a drain and refill on the CVT a year ago and had Nissan Flush and replace the coolant last March for preventative measures. This issue started about a year ago and hasn’t gotten any worse. The near stall condition when coming to a stop doesn’t happen every time. I have no check engine lights or stored codes. The vehicle doesn’t consume any oil and the plugs look good and clean. Also the Plug wells are clean and NOT leaking oil around valve cover gaskets “yet”. I have not cleaned the throttle body yet in fear of the relearn process being and issues. I have read horror stories of people cleaning the throttle body and the car not running right after.

Any Advice would be great! Thank you in advance.
