My car doesn’t seem to like cold starts. It fires up immediately, but once I try to move the RPM drops drastically and the car almost stalls, even when giving more throttle. It lasts 2 or 3 seconds, then the car drives but it is still a bit hesitant for a few meters.
No problem after that, or if the engine has been run 1 or 2 hours before.

What could be the cause ?
