09 c63 Check Engine Light

Ok so yes, I'm new here. I actually come on here a lot to read when I have issues and it's been a tremendous help. 😃
So this morning when I got in the car, everything was fine. I drove about 20 miles, stopped for coffee and when I cranked it back up had the CEL. The car seems to be running fine with the light on. No other issues with running rough, it doesn't seem to be sluggish. I noticed a slight whistling sounds yesterday(it sounded like a turbo whistle but I don't have a turbo) so I'll def check the MAF sensor hose.
I've read other threads from 2012 and 2014 to see if maybe mine seems the same and really it does. I'm just wondering if there's something new I'm not seeing. I have not had the code read yet, but as long as it starts on my lunch I'm taking right down the street to the Autohaus shop, but I just want to get an idea to make a list of all the things it could be.
Any help and suggestions would be greatly appreciated.

Need a mod list, and a OBDII scan.

With out those can't help much.

Get the code read. Leaky intake manifold. Check the gaskets.

Get some brake cleaner and spray around your intake manifold (I actually just fixed this issue on mine last month) if it starts to choke you have an intake leak. Post the codes here once scanned.

Get the code read. There are just too many things that can cause the Check light to come on.

The code is exactly as I thought it would be. It's the P0171 misfire code.
I drive the car about 30 miles home today and it ran just fine.

I haven't done any mods. I'm pretty sure it's all stock. Besides the stereo system.

Generally you'd have lean codes for both banks if it was the PCV.

😃

I added fuel injector cleaner to the tank on Wednesday night and the light went off yesterday afternoon. All seems well.

Had the same codes on my old car. Cleaned out the filter and removed all the dirt. Wiped the sensors and reset the CEL codes.

That seems awfully random.
