I own a 2020 sti and i have like 8.5k miles on it. I flat foot shifted I would say about 5-20 times in the span of 2 days. Now, when I do a cold start, white smoke comes out of the exhaust and it really smells like burnt plastic or rubber or something. My coolant keeps dropping but when I go out for a drive and check it, it comes back and I am so confused on what is going on with my car. I also had a cylinder 4 misfire but it isn’t occuring anymore and only happened twice. Plz help!

Any running rough of loss in power? Any changes when in boost vs not in boost? Does the white smoke go away when the car warms up?
