After cleaning the throttle, it is necessary to rematch it with a computer because cleaning the throttle is usually done due to clogged air passages. At this point, the computer has made some related adjustments based on the clogged air passages. Once the throttle is cleaned, it is essential to perform the corresponding computer rematching. The throttle is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to produce power. Symptoms of a faulty throttle: 1. The EPC light on the dashboard will illuminate; 2. Difficulty starting the engine when cold; 3. Frequent stalling when the vehicle is coasting; 4. Unstable idle and black smoke emissions.

Is There a Difference Between Private Gas Stations and Sinopec's Fuel?

Private gas stations and Sinopec's fuel have differences, which are: 1. Different production sources: The gasoline from private gas stations is produced by local refineries; Sinopec's gasoline is produced by Sinopec. 2. Different production equipment: Private gas stations have relatively simple production equipment; Sinopec's production equipment is more comprehensive. When the engine is running, the fuel supply system injects gasoline into the intake manifold or combustion chamber, where it mixes with air. The spark plug then ignites the combustible mixture, and the combustion of the mixture pushes the piston downward, enabling the engine to perform work. Gasoline cannot be completely burned within the engine, so over time, carbon deposits will form inside the engine. Carbon deposits are harmful to the engine, so they must be cleaned regularly. Otherwise, it can lead to increased fuel consumption and reduced engine performance.
