Simple question from a "newish" owner

[jauloz]

I have owned my X for almost a month now, living in -20C weather, I wonder if you guys have the same situation with idling, just to confirm if mine is normal.

Cold start at 1100 rpm, slowly drops to ~650, pretty normal right?

but my warm start would stay on 1100 rpm forever. Is this normal too?

Also, warm car right after being driven, put it in "P", car idle at 1100 rpm too!

With resonator deleted and 1100rpm warm car idle, exhaust smoke is ridiculous, it almost like my car was on fire or something lol. Winter effect
