I don't know that public opinion has been filtered out, but it has been running for a while! Then the car ran out of power and couldn't get a taxi! After pushing, the idle speed is particularly low, and the throttle car will stall! festival Without the protection of air filter, the intake system, exhaust system and even cylinder piston will be damaged.

Is the throttle clean now?

See if the oil is seriously polluted. If it is dirty, change it.

Let the car idle and see if the exhaust pipe is normal. Otherwise, the three-way catalyst may be blocked. Please delete it and try again. If the displacement increases, try to refuel. If not, it will improve.

I don't know what kind of air flowmeter the bus is. You found it. If it is behind the throttle, clean it, because there will be oil pollution behind the throttle and a lot of soil will be stained on it, which will affect the intake volume and the calculation of intake volume.

Spark plugs need to be checked. It's simple. Just unscrew the next one and have a look.

It is necessary to look at the fuel injector again.

The most difficult thing is the intake and exhaust valves and cylinder pistons. It's all done. If it is improved and the engine can touch the car, inject carburetor freshener from the throttle and clean the intake and exhaust valves.

Finally, if the above operation feels that the engine condition has improved obviously, you can let the car idle for a period of time and run in the engine cylinder and piston in the form of hot grinding (this is also a stopgap measure, and you will have to go to the repair shop if it is really not possible).

Pay attention to the safety of the above operations and do it yourself. If you don't know much about cars, take them to the repair shop and give them to the maintenance master.
