Reasons for steering wheel shaking when the air conditioning is turned on while driving: The throttle body is dirty, which affects the engine. If the air conditioning is turned on at this time, it will increase the engine idle speed, leading to steering wheel shaking. Areas to check for air conditioning-induced shaking: 1. Check the high and low pressure of the air conditioning system, as excessive pressure can cause a sudden increase in engine load; 2. Inspect the engagement of the air conditioning electromagnetic clutch; 3. Examine the engagement of the air conditioning electromagnetic clutch; 4. Verify if there is an excessive amount of refrigerant. If the steering wheel shakes when the air conditioning is turned on while driving, it is recommended that the owner promptly visit a 4S shop or a professional auto repair shop for inspection and maintenance.

What Causes a Car to Stall When Accelerating After Starting?

Stalling when accelerating can be caused by the following reasons: 1. Dirty throttle body: This condition can cause the throttle plate to open less or become stuck during acceleration, leading to stalling. In this case, clean or replace the throttle body and perform throttle adaptation. 2. Faulty ignition coil, open or short circuit in the coil: Check by replacing with a new ignition coil for comparison testing. 3. Dirty fuel filter: The fuel system may not function smoothly during acceleration. Replace the fuel filter in this situation. 4. Faulty fuel pump: The fuel pump cannot maintain proper fuel pressure or provides insufficient fuel injection while driving, causing stalling during acceleration. Replace the fuel pump and clean the fuel tank if necessary. Also, inspect the throttle body and fuel injectors.

How long does it take to drive after applying car undercoating?

How long it takes to drive after applying car undercoating depends on specific circumstances, with key factors including the craftsmanship level, quality and performance of the protective coating, and weather conditions. Normal driving can only resume after the protective coating has completely dried. The drying process can involve natural air drying after spraying or using fans to enhance air circulation for faster drying. Generally, fan-assisted drying saves more time than natural drying, but it may negatively affect the uniformity of the coating film. Before applying undercoating, the car must be lifted with a jack and the undercarriage cleaned to remove dirt, rust layers, and moisture. It's important to note that areas such as the exhaust system, suspension, and brakes should not be sprayed. These parts need to be covered with materials like newspaper. A specialized undercoating spray gun is then used to evenly apply the undercoating product to the undercarriage, followed by natural drying.

What is Skip Downshifting?

Skip downshifting refers to when a driver does not follow the normal sequential downshifting pattern of 5-4-3-2-1, but instead skips a gear level, such as 5-3-1 or 4-2, directly downshifting past one gear. Below are related explanations: 1. Skip Downshifting: It is possible to skip gears when downshifting, but the gear selected must match the vehicle's speed. If the speed allows, skip downshifting can be performed. However, before skipping a gear, always remember to press the clutch first, and then directly downshift when the speed matches the desired lower gear. 2. Precautions: Although skip downshifting is possible, it must be done according to the vehicle's speed. Driving at 'high speed in a low gear' can cause gear collisions, potentially damaging the engine and transmission.

What Causes the Brake Noise When Driving a Mercedes-Benz GLC?

Mercedes-Benz GLC may produce brake noise during driving due to worn brake pads that need replacement or repair, road bumps, or foreign objects lodged in the brake pads. Reasons for Brake Pad Wear: Frequent braking during turns causes uneven force distribution on the left and right wheels, leading to wear. One side of the brake disc may become deformed. The brake caliper pistons do not retract uniformly. Significant differences in the length of left and right brake fluid lines. Inconsistent braking timing between the left and right brakes. Issues with the ABS control strategy result in unequal pipeline pressure, causing uneven wear. Reasons for Foreign Objects in Brake Pads: Driving on unclean road sections.
