Emgrand EC7 computer diagnosis fault code is P00 16. What is the cause of jitter?

The fault code of Emgrand EC7 computer diagnosis is P00 16. Jitter is caused by "carbon deposition".

Understanding of carbon deposition?

Carbon deposition is a kind of combustion substance produced by unsaturated olefins and gums in fuel at high temperature during engine operation. It can accumulate in various parts of the engine, such as the intake and exhaust system; Fuel chamber; Fuel injectors, etc. It has the characteristics of oil absorption, which will make the incompletely burned gasoline turn into carbon deposit again, and it will become thicker and thicker. This is what we call carbon deposition.

Harm of carbon deposit to automobile

(1) The reason that can't be ignored is "carbon deposition", which 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.

(2) The second is to increase fuel consumption and increase your economic burden.

(3) Third, it is difficult to start a cold, that is, it is difficult to strike a light and it is not easy to get a taxi. Finally, serious carbon deposition in the combustion chamber will also lead to cylinder knocking, and low-speed acceleration will produce noise, damage the piston and crankshaft, lead to engine heating, and seriously affect the safety of the car. Then the discharge exceeds the standard, which not only fails the annual inspection, but also directly aggravates the harm of environmental pollution.

Removal method of carbon deposit:

(1) Clean the throttle valve

Take off the engine decorative cover, remove the throttle, clean it with carburetor cleaner, dry it with cotton cloth and install it.

(2) Clean up the carbon deposit inside the engine.

Open the oil cover, pour the whole tank of cleaning agent (mixed with old oil), cover the oil cover, ignite the engine at idle speed 10 minutes, and then turn off the engine. Clean the carbon deposit inside the engine. This cleaner can dissolve the deposits such as sludge, colloid, moisture and metal debris inside the engine, reduce the pollution of new engine oil and prolong the service life of the engine.

(3) Remove the carbon deposit in the air intake system

Buy a bottle of cleaning agent for air intake system, pour it into the liquid storage tank of special cleaning equipment, connect the air intake system, and suck the cleaning agent into the air intake by vacuum to achieve the purpose of cleaning.
