'17 R/T Idling Funny
 

Hi all - wondering if anyone has experienced this. I've been driving my new-to-me 2017 Charger R/T for about 9 months now. It has 29k miles on it. Two days ago I was idling at a light and felt the car shudder. What's happening is when I roll to a stop, foot on brake and in gear, the idle will settle to around 600 RPM (which is smooth) and after a few seconds drop to 500 RPM which causes a noticeable shudder while it's idling. It will remain there until I accelerate again, and then do the same thing at the next stop. It does not do it in Park, and it doesn't do it all of the time - I'd say about 95% of the time. Only when warmed up and in both Sport and regular mode. It almost feels like a load is being put on the engine that it's not compensating for. Any ideas?

It is - I was just wondering if it was "normal." The climate control isn't adjusting for sun load properly either - it needs calibrated. I guess I'll bring it in!

Nope. Not normal.
