The reasons for a car running normally on gasoline but experiencing jerking and hesitation when running on gas are: 1. Issues with the idle control system, gas system, or ignition system; 2. Carbon deposits causing incomplete combustion of gasoline. The causes of carbon deposits in the engine: 1. The engine runs for short periods over a long time; 2. The gasoline contains a large amount of water; 3. The gasoline contains a large amount of gum; 4. Poor oil seal of the engine intake valve. Methods to remove carbon deposits in a car: 1. Disassemble and clean various engine components; 2. Perform a fuel system cleaning using an intravenous drip method; 3. Add fuel cleaning agents to the fuel tank. Benefits of cleaning engine carbon deposits: 1. Improve the car's horsepower; 2. Save fuel consumption; 3. Reduce the knocking point; 4. Promote environmental maintenance; 5. Extend engine life; 6. Enhance brake accuracy.
