2006 307 1.4 16v misfire failure

Good evening, I have 2006 model 307 1.4-16 valve, there is no LPG in the vehicle. Gasoline vehicle constantly gives 4 cylinders ignition failure. Now it does not give fault code, it does not light up on the lamp, but the vehicle is singing 4 cylinder spark plugs are always getting wet. Do you think it can cause malfunctioning good evening

Does your vehicle have an engine top cover?

There is a coil failure, sir. Take out the coils of the coil and look at the copper ends. If there is oxidation, it is most likely malfunctioning.

yes there is an engine insulating cap.

The 2006 model, that is, new types of coil tires come out, when I disassemble it comes complete.

When the spark plug is inside or wet outside or wet outside, when you remove the coil, is there a water reduction in the spark plug bearing or wet one? If you are experiencing water shortage, you may have burnt the gasket.

In the place where the wetting plug has the ignition nail, that is, the fuel coming from the injector, there is no water reduction in the car, there is no compression, there is a compression clock. When I go out, it turns out 150. But the car is singing and blowing up no traction

There are coil connection cables. The air goes to the coil under the filter box. One of these cables may be broken. Check them also. Remove the air filter box. Check the cables going to the coil.
