Automatic transmission vehicles are forced to frequently downshift; 3. The engine power decreases, and exhaust emissions exceed the standard; 4. The engine shakes, the fault light comes on, and the car frequently stalls; 5. The exhaust pipe temperature continuously rises, reaching the ignition point of nearby components, which can easily lead to spontaneous combustion.

Replace the three-way catalytic converter; 3. Add gasoline additives and avoid using inferior gasoline and gasoline additives.
