Hey Scotty, my 2013 dodge dart 2.0 shakes a lot at idle and the idle looks a bit low the rpms go up and down when you turn the a/c or headlights on it only has 75k on it so I’m a little bit concerned only problem I’ve had with it thanks.
This might be a lot of things but let's start with the basics: Clean the intake, sensors and throttle, replace the spark plugs, check the engine air filter, look for vacuum leaks, and connect and OBDII scan tool inspect fuel trims and O2 sensor readings.
After completing all of those, put your car in N, and rev it up to 4k rpm for at least 45 seconds - I had a Corolla with an extreme case of that issue and that would be the only thing that helped.
(BTW, hopefully you've followed the manual and replaced the ATF at 60k, it's better to do it every 30k since your tranny the Hyundai-Kia A6F24 really doesn't like running on dirty oil)
Well realize those Dodge darts are really really badged Fiats all kinds of Italian parts on them. But start with a tune-up and check for vacuum likes and do my video. Make your car run better with a little spray cleaner and pray that fixes it. They were not very good cars realize that
