As shown in the picture, is it necessary to clean up the detected carbon deposit for a new car that has just traveled less than 10 thousand kilometers?

Is this carbon deposit in the combustion chamber? Nice equipment and probes. Personally, I feel that the problem of carbon deposition is not serious. Last time, my valve cover gasket leaked oil and deposited carbon seriously. It's far more than that, and there's nothing wrong with driving. Of course, I'm not happy to see it, so I'll clean it myself.

1, you should have a spark plug sleeve and a torque wrench, and know the tightening torque value of the spark plug and ignition coil screw of your model.

2. Prepare detergent. I use Anceaux APF. It is recommended to use cleaners made of strong wind materials. It's not expensive. At least two bottles should be prepared, as well as a set meal with syringes. The syringe should be larger and the hose should not be too long.

3, it is best to warm the car, idle for a while or drive for a while, turn off the engine cover, remove the ignition coil, and remove the spark plug.

4. Spray foam cleaner into the combustion chamber. After fifteen minutes, the syringe draws out the residual liquid and can spray it again. Don't dump the waste liquid indiscriminately, and treat it after bottling.

5. Recover after washing. It's okay if you can't smoke clean at night. It will burn out after starting, and the exhaust will be clean after a while. Pay attention to tighten according to the specified torque value.
