What Causes a 170 Gasoline Engine to Start and Then Stall Immediately?
1 Answers
170 gasoline engine starts and then stalls immediately for the following reasons: 1. Spark plug: The spark plug loses its ignition capability. 2. Throttle: The throttle malfunctions. 3. Carbon deposits: Carbon deposits cause incomplete combustion of gasoline, leading to engine shaking. Engine carbon deposits have a significant impact on the car. First, they reduce engine power, resulting in uneven power output and gradual attenuation—in other words, the engine becomes increasingly weak. Second, they increase fuel consumption, adding to your financial burden. Third, they make cold starts difficult, meaning the engine is hard to ignite. Severe carbon deposits in the combustion chamber can even cause cylinder knocking, producing noises during low-speed acceleration and damaging the pistons and crankshaft. This leads to engine overheating, severely compromising vehicle safety. Additionally, carbon deposits cause excessive emissions, not only failing annual inspections but also worsening environmental pollution. 4. Transmission load: Overloading the transmission degrades the quality and friction characteristics of the transmission fluid, increasing friction and wear. This results in transmission noise, and sludge (impurities or dirt) can form inside the transmission (e.g., in the valve body), causing issues like jerking, gear disengagement, impact, slipping, stalling, abnormal noises, delays, overheating, and oil leaks.
