What does this mean? RPM fluctuating while parked
This is what happens when the car is in park (or stopped at a stoplight or something). It’s 100 degrees Fahrenheit outside, AC is on. Idk if you can hear on the video, but you can like hear the engine (?) revving/shuddering or something pumping/cycling (?).
I’ve dealt with the typical Chevy sonic overheating thing lol.. sigh. At worst, it stalls after this sort of thing. Stalling hasn’t happened in a while though, since I did a couple tweaks.
I did the PCV fix kit, changed spark plugs and coils, and fixed a coolant leak.

How do I remedy/avoid this?
