What Causes Engine Shaking at Idle and Lack of Power During Acceleration?

The primary cause of this issue is the accumulation of carbon deposits in components such as the throttle body, intake manifold, and valves. When the engine is cold, these deposits absorb some gasoline. As the engine warms up, the gasoline evaporates, leading to an overly rich air-fuel mixture during idle, which results in unstable idle conditions. Below is a detailed explanation: If the three-way catalytic converter is clogged, it will directly affect the vehicle's acceleration performance and also increase fuel consumption, causing a noticeable lack of power during acceleration. Therefore, it's essential not only to inspect the throttle body and idle control valve but also to check for excessive carbon buildup and dirt in the intake manifold. Excessive deposits can alter the cross-sectional area of the air passage, preventing the engine control unit from precisely regulating the idle air intake. This can result in an air-fuel mixture that is either too rich or too lean, leading to abnormal combustion and engine shaking. Additionally, it's important to inspect the carbon canister for any potential malfunctions.

Is there a fee for re-inspection if the exhaust fails?

Generally, there is no charge for re-inspection if the exhaust fails. You can simply get a checklist stamped. Repair at a garage: This method involves replacing all necessary parts such as the fuel injectors, catalytic converter, and any other components that need replacement or adjustment. After these repairs, it becomes easier to pass the exhaust inspection. Cleaning the exhaust system: First, address the fuel injectors—cleaning the fuel system is usually sufficient, so it's recommended to use a fuel additive before inspection. If the injectors are beyond cleaning, the catalytic converter may need replacement. Alternatively, removing the air filter might also help. Replace the spark plugs and use 97-octane gasoline before the test. Rinsing the exhaust pipe with water can also temporarily improve exhaust emissions.

Is the highway administration towing service free of charge?

Highway administration towing service is not a free service. Precautions: When a vehicle becomes inoperable on the highway and requires towing, some vehicle owners may attempt to save costs by having a friend tow the vehicle. This is considered illegal. If towing is required on the highway, it is necessary to call professional towing or rescue vehicles. Towing services provided by insurance companies and 4S stores: Some towing services offered by insurance companies may be free within a specified mileage limit. Once the mileage exceeds the limit, charges will apply according to their own fee standards. Similarly, some brands at 4S stores follow the same charging policy, while others may offer free towing services. Road administration towing services do not have a free mileage allowance and will charge based on the towing distance.
