The reasons for car shaking during cold start are: 1. Excessive carbon buildup in the throttle body; 2. Aging engine mounts; 3. Abnormal cylinder operation; 4. Unstable idle speed; 5. Malfunction in the ignition system. Solutions for car shaking during cold start include: 1. Cleaning the fuel system and checking for carbon buildup in the idle speed control valve; 2. Inspecting spark plugs for excessive carbon buildup and replacing them if necessary; 3. Checking fuel pressure and replacing components as needed; 4. Verifying that the battery voltage is within the specified range. The steps for starting a car are: 1. Press the brake with the right foot and the clutch with the left foot; 2. Shift to neutral, insert the key, and start the engine; 3. Keep both feet on the brake and clutch, shift to first gear, and release the handbrake; 4.

What does the ECTPWR light mean?

ECTPWR light indicates the activation of the car's power mode, which delays upshifting to enhance power output and increase the vehicle's speed. The owner can check if there is an ECTPWR button near the gear shift lever. Pressing this button will turn off the ECTPWR light. To reactivate this mode, simply press the button again. Additional information: ECTPWR is equivalent to the car's sport mode. Pressing this button alters the engine's operation mode, and the transmission's shift logic will also change accordingly. In this mode, the car's power will be stronger, and the throttle pedal will be more responsive. However, prolonged use of this mode will increase fuel consumption and accelerate engine wear.

Can a Modified Car Grille Pass the Annual Inspection?

Whether a modified car grille can pass the annual inspection depends on whether the manufacturer has registered the modification and whether the vehicle matches the photo on the registration certificate. Additional information: 1. The main functions of a car grille are to provide air intake for the radiator, engine, and air conditioning, protect internal components from external damage while driving, and enhance aesthetics to showcase individuality. In automotive engineering, the grille is used to cover the body to allow air intake. Most vehicles have a front grille to protect the radiator and engine. 2. The grille can be modified before purchasing a new car without affecting registration and annual inspection. If you want to modify the grille, it is recommended to do so after the vehicle has been registered. Modified grilles will not affect the vehicle's ability to pass the annual inspection later on.

Can Small Body Kits Pass the Annual Vehicle Inspection?

If the small body kit has been registered with the vehicle management office, it can pass the annual inspection. If not registered, it will not pass the inspection. Any changes to the vehicle's body color, model, performance, purpose, or structure, including replacing the frame, body, or engine, require applying for modification registration with the vehicle management office. Small body kits are considered alterations to the vehicle's appearance, so they must be registered with the vehicle management office. Otherwise, they may be subject to penalties by traffic police or fail the annual inspection. Vehicles with any of the following conditions must undergo the necessary procedures before being inspected: discrepancies between the vehicle's condition and the records on the driving license or file; damaged, incomplete, or illegible license plates or driving licenses, or self-made license plates; modifications, model changes, or technical alterations without proper approval and modification procedures; failure to display the unit name and enlarged license plate characters as required; improper installation of alarms or warning lights; failure to pay road maintenance fees or insurance as required.

What to Do If the Mercedes Fuel Tank Cover Won't Open?

Many vehicles have an emergency fuel tank cover release located under the panel on the fuel tank cover side of the trunk. Pull the emergency release handle with moderate force while pressing the fuel tank cover. If it still won't open, it indicates a damaged motor lock, which needs to be replaced. It could also be due to the fuel tank cover spring losing elasticity. Owners can address this by adding a small spring to the rubber pad on the fuel tank protrusion to increase the cover's elasticity. Regular cleaning of the fuel tank cover is recommended. There is usually a drainage hole underneath the cover. If this hole gets blocked, it can easily lead to water accumulation during car washing.
