The tire pressure is fine I checked it 2 days ago. I should probably change the filters though.

Try keeping at 3.2k +. I don't think your plugs are an issue since you just bought car so had to pass CA smog. Of course new plugs are always good.

Damn I'm such a newbie lol. I've driven a manual car before but it wasn't a sports car and this my first car with manual. So I've been lugging my engine for like 3 weeks I hope I didn't screw things up too bad.
