Daewoo 225-7 can't add oil in the throttle self-test.

The oil circuit is blocked and the exhaust system is out of order.

1, the oil circuit is blocked. If the automobile oil circuit system is blocked and the fuel cannot be fully delivered, resulting in incomplete combustion of fuel in the engine cylinder, the engine power will be reduced, so it is necessary to clear the oil circuit in time.

2. Exhaust system failure. The fault of the exhaust system is that the three-way catalyst or exhaust pipe is blocked, which leads to the failure of the automobile throttle, so it is necessary to clean the three-way catalyst or exhaust pipe.
