First of all, hello friends, my car is a Peugeot 308 2009 model, LPG has never been installed before, when we start this car, the idle moves by itself and the car shakes, and the fault light is on, and the screen says exhaust emission fault, I am about to go crazy, we changed the oxygen sensor, coil etc. many things, I would appreciate it if you could help.
