Mark 30 1 throttle body neutral position consistency

Mark 30 1 The neutral position of the throttle body is consistent, which is a fault, because there is too much carbon deposit in the intake system and the intake valve root, resulting in too high mixture concentration during cold start. Solution: Clean the air intake system. The throttle is dirty and the air intake is insufficient. Solution: clean the throttle. The speed of the starter can't meet the requirements.

Precautions:

Carbon deposition will cause insufficient combustion of gasoline and make the engine shake. The influence of engine carbon deposition on automobiles is considerable. First, the engine power is reduced, that is, the power output is uneven and gradually decays, in other words, it is getting less and less powerful.

Increase fuel consumption and increase your financial burden. It is difficult to start a cold start, that is, it is difficult to strike a fire, and it is not easy to get a taxi. Finally, the carbon deposition in the combustion chamber is serious, which can even lead to knocking.

Low-speed acceleration is noisy, causing damage to the piston and crankshaft, resulting in high temperature of the engine, which seriously affects automobile safety. Then the discharge exceeds the standard, which not only fails the annual inspection, but also directly aggravates the harm of environmental pollution.
