So when driving in sport or sport plus, the idle remains at close to 800-900 after getting to operating temps but when turning off sport/sport plus the idle drops close to 600 even after warm. I almost always drive in sport so didn’t realize any differences until today. Just filled up full tank and added Techron as starting point.

Normal behavior.

Good. Give it some real exercise and reassess the idle instability after 3/4 of the tank.
