2020 Mitsubishi Jin Xuan starts very slowly after braking.

It may be caused by excessive carbon deposition in the engine.

There are several situations in which the engine has too much carbon deposit, which will lead to slow start after braking. For example, when too much carbon is deposited in the combustion chamber, the compression ratio of the engine will increase, forming many hot surfaces, causing premature combustion and deflagration, shortening the service life of the engine and greatly reducing the power and economy of the engine; Carbon deposition in the nozzle will cause different fuel injection quantity of each cylinder nozzle, resulting in engine jitter or blockage; When there is too much carbon in the spark plug, the spark plug will not work because of air leakage, and the engine will shake; Too much carbon deposit in the throttle valve leads to unstable idle speed, decreased power and even automobile failure.
