Vibration and popping sounds from the exhaust.

Hello friends, my car is a 2012 Peugeot 206+ 1.4 petrol/LPG. This morning, after starting the car and waiting for a while, it starts to accelerate on its own, vibrates, and makes a popping sound from the exhaust. It stops after a while. I've changed the MAP sensor, spark plugs, and injectors, but the problem persists. Has anyone experienced a similar problem or found a solution?

Coil?

Throttle body and air leaks are particularly common in 206+ models. Instead of randomly replacing parts, have a skilled mechanic check it using a computer.
