How to deal with the exhaust blockage of Ou Man 560 automatic gear?

You can knock the outside of the exhaust pipe with a rubber hammer to make the carbon accumulated in the exhaust pipe fall off, and then slowly pour it out from the other end of the exhaust pipe.

The following is an introduction to the prospect of exhaust pipe blockage: 1. Low acceleration efficiency: If the engine is idling unsteadily and cannot refuel, and the car feels breathless in the middle of long-distance driving, it may be because the exhaust pipe is blocked, which leads to poor exhaust, less intake and lower engine power. 2. The automatic transmission is frequently forced to downshift: when the engine power drops due to the blockage of the exhaust pipe, the driver will step on the throttle deeply to accelerate and make the throttle fully open. At this time, the car will control the automatic transmission to downshift according to the state of the throttle. 3. There is slight backfire when the engine refuels: the blocked exhaust pipe will make some exhaust gas stay in the cylinder, dilute the mixture and slow down the combustion speed. When the intake valve is opened, the mixture is still in the combustion state, so it will flow back into the intake pipe through the opened intake valve, causing backfire.
