1 1 Camry What should I do if I waste engine oil after cleaning up carbon deposits?

Adjust the throttle. After the carbon deposit on the throttle is cleaned up, the fuel consumption increases because the throttle can be adjusted automatically. After the pores of the throttle valve are slowly blocked by carbon deposits, the throttle valve will be adjusted to a relatively large state to ensure the air intake at idle speed. After cleaning up the carbon deposit, the throttle hole still becomes larger, and the throttle valve needs to be adjusted.
