Car engine shuddering, high fuel consumption repair

 Today this car has only run more than 20,000 kilometres, the engine shaking particularly strong,

idle speed is also normal, the dashboard also does not have any fault lights,

the owner responded to the fuel consumption than before to much higher. When this happens, it is usually caused by the aging of the spark plugs, and many people want to go to the repair shop once they hear that they want to change the spark plugs, now the labor costs are very high, go to the repair shop for a change, no several hundred dollars is not possible. Today we replaced the spark plugs ourselves. I bought new spark plugs from the internet and it only cost me a few tens of dollars, and I was given a set of tools to remove them. Next, let's start replacing it, unplug the ignition coil, the top plug,

pull out the ignition coil, the spark plug is underneath, next we use the special spanner for spark plug to take it out, you see this old spark plug gap is not very big?

If the spark plug gap is too large,

it will lead to inadequate combustion of the mixture, which will eventually lead to engine shuddering and higher fuel consumption. If you feel that your car is not as powerful as before, and the fuel consumption is higher, replace the spark plug and basically restore the state of the new car. After the spark plugs are removed, we put the new spark plugs in,

tighten them with a special spanner and finally put the ignition coil back in and plug in the ignition coil.

You come down, we start the vehicle, it starts successfully in one go and see that the engine is no longer as shaky as before,

isn't it easy to repair the car? I believe that the fuel consumption can also come down, learn about car repair every day, you can also do the car repair yourself.
