I have noticed in my new 2025 CX-5 that when in park with the engine running, it idles up a few hundred rpm and then goes back down. It doesn do this all the time but I have noticed is a couple of times. I was thinking that maybe the AC compressor was kicking on and causing the momentary jump in idle. It's been a really long time since I have had a 4 cylinder car and thought that maybe this is something normal. Please share your thoughts. Thank you
