Hi guys. I bought a Mazda 3 2014 gs few months ago. Everything is fine. But whenever I start the car the engine is revving for about 30sec and then it stops or if I shift to R/N/D then it stops as well. But now since the winter is coming and days are colder the revving last even longer. So I am wondering is there a problem with the engine or something else?

Welcome aboard.

It's known as a fast idle, always happens on cold starts and is intended to bring the cats up to temp quickly. Perfectly normal.

it was designed that way because it’s heating up the cats quickly on a cold start, I believe it was also written in the owners manual

(and the exhaust sounds soooooo good LOL
