Cold Start Low RPM then normal

I own an 04 AP2 and now that the weather is getting cold in Northeastern USA I've been noticing issues starting up. During first start of the morning the car would crank slow then I notice that the car idles around 500 rpm then goes into the normal cold start 2k rpm.

Here's a video with a similar issue on an AP1 i found on youtube.

There are mornings where it's worse than the video above and stays on low rpms for 3 seconds max depending how cold it is outside. Once i get it running it starts up normally if i turn it off then start it back up again.

So far i went to have my battery checked at the dealership i bought it from and autozone and the "claim" that my battery is working perfectly fine. They had me turn off and turn on the car. And of course i couldnt show them how the car acted under cold starts because by the time i take it to them, the car isnt cold anymore. I left my car at the dealership overnight for them to test but it was during the end of the summer so it wasnt that cold.

I also changed my spark plugs and tried an ECU reset. No good.

Would a rattling CAT be related in any way? When I'm driving i hear a slight rattle when I'm driving around 2800 rpm. trying to rule out everything as much as possible
