What is the reason?

When the power of the vehicle is insufficient, it will lead to the inability to increase the speed quickly and increase fuel consumption. Then the question is, what is the reason for the lack of power in the car?

There are many reasons for the lack of automobile power, and the treatment methods should be targeted. For example, some cars are short in age and newer cars lack power. It is necessary to consider that the quality of the added fuel is not up to standard. In this case, only replacing qualified fuel can solve the problem.

If some old models lack power, it may be the cause of excessive carbon deposition. Too much carbon deposition will lead to the intake air mixture not meeting the requirements, and the intake and exhaust valves will not be closed tightly. So the carbon deposit should be cleaned up. For the serious problem of carbon deposition, it is necessary to remove the throttle valve, cylinder head, valve group and other parts for sufficient carbon deposition cleaning.

The lack of power in some vehicles is caused by the reduced efficiency of spark plugs. If the spark plug is used for a long time and is not replaced by mileage, then the spark plug needs to be replaced in this case.
