cold start

Good day, I have a 2021 mustang gt, 12000km. This morning on a cold start, the car is seriously struggling, It's only -10 C in my garage. The rev counter is just going up and down, the vacuum gauge is not stable at all, the car shakes while it does that, and the engine sound is not right as...

Happened for the first time a couple weeks ago and again this morning, both times were auto started with the key fob, shut car off and start with push botton and it’s fine, both times the car had a wash (underside included) and then sat for about a day and a half in somewhat cold weather(-5...

Hey everyone. I got a 2015 V6 about a week and a half ago, and I notice that on cold starts the motor shakes almost as if the idle is too low. Once the engine is hot, the shaking ceases. Any ideas to what this could be? I have seen a lot of threads of high RPM at cold start but nothing like...
