Possible? Would an exhaust leak cause it or even contribute to it?

Possibly related but when car is cold, and stopping at lights for example the revs take a long while to settle when holding it on the brake and a bit more so with rear demister on

That does sound like an icv/air leak issue.  Exhast leak would increase consumption/noise/smell
