How to deal with the serious carbon deposition in Fit?

Fit carbon deposit is serious, so the following treatment methods can be considered:

1. Clean the throttle valve and air intake: the carbon deposit in the throttle valve and air intake will affect the normal operation of the engine, resulting in power loss and fuel consumption increase. Cleaning the throttle and air intake can effectively remove carbon deposits and restore the performance of the engine.

2. Use fuel additives: Fuel additives can help remove carbon deposits, improve fuel quality and reduce carbon deposits.

3. Replace the spark plug and cylinder liner: Carbon accumulation in the spark plug and cylinder liner will lead to the decrease of ignition energy and make the engine work abnormally. Replacing spark plug and cylinder liner can improve ignition energy and solve the problem of carbon deposition.

4. Adjust the ignition advance angle: If the ignition advance angle is too small, it will lead to insufficient combustion and carbon deposition. Adjusting the ignition advance angle can make the combustion more complete and reduce the generation of carbon deposit.

5. Replace the air filter: Dirty air filter will lead to insufficient air intake, insufficient fuel combustion and carbon deposition. Replacing the air filter can increase the air intake and reduce the generation of carbon deposit.

It is necessary to choose an appropriate treatment method according to the actual situation. It is recommended to go to a professional repair shop for cleaning and maintenance.
