RPM fluctuation with constant speed / "bucking"
I've come across an issue with my 2019 C63 where with constant speed (CC on) the car starts to "buck" slightly. I've read that their are multiple areas where this issue might be stemming from transmission, coils, injectors, so if anyone can chime in with their own experiences similar to mine that would be apricated.
I'm currently at 93K miles and my last transmission service was at ~60k. I have not replaced my coils yet but got new spark plugs at 85k.
There is also a video of what is happening attached - RPM issues
Thank you.
