Why Can't a Natural Gas Vehicle Accelerate When Pressing the Throttle?

[OCarson]

Introduction to the reasons why a natural gas vehicle can't accelerate when pressing the throttle: This situation may be caused by a damaged air flow meter, insufficient cylinder pressure, or a faulty ignition coil. Check if the gas pressure valve has any issues, as insufficient pressure could also be the cause. A dirty throttle position sensor or voltage imbalance can also prevent acceleration. More related details: 1. Try to determine if the vehicle's throttle pedal is malfunctioning: When pressing the throttle, the cable moves the throttle valve (i.e., the throttle), which has a position sensor. The control unit uses the signal from the throttle position sensor to determine the throttle opening and then calculates the corresponding signal voltage. Based on this voltage, it determines the fuel injection amount. 2. Inspect the engine's fuel system: If low-quality gasoline is used, it may lead to fuel pump burnout, catalytic converter failure, piston issues, etc., directly affecting engine power and causing symptoms like engine stalling or inability to accelerate. If the spark plugs are degraded or low-quality spark plugs are used, it can also result in poor acceleration or acceleration shuddering.
