Good luck to everyone. I have a peugeot 307 vehicle, when the diesel tank is less than half a tank, I put an injector cleaner on the tank, I used the car for a little bit, but the car started to work like a tractor. Now my question is that there is no sound when the vehicle is idle at the moment, but when the gas is pressed or when the vehicle is walking, it makes a click or decrease in parallel. One master looked at the vehicle, engine wrapped around the bed, said do not move the vehicle, said a master, the injector said, I was surprised. I did not understand what was the fault light in the car or the problem is not gone. I would be happy if you help
