Dirty throttle body; excessive carbon deposits inside the engine; faulty spark plugs or ignition coils; clogged fuel lines or fuel injectors. Methods to address engine shaking: Check the idle control valve for carbon buildup; inspect spark plugs for excessive carbon deposits and replace if necessary; check fuel pressure, clean the fuel system, and replace components as needed; examine the condition of high-voltage wires and ignition coils. Introduction to engines: The car engine is the device that provides power to the vehicle, determining its performance, fuel efficiency, stability, and environmental friendliness. Car engines are categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid motors. Among them, gasoline and diesel engines are reciprocating piston-type internal combustion engines that convert the chemical energy of fuel into the mechanical energy of piston motion to deliver power.

Can You Pass Subject 1 with the Streamlined 500 Questions?

The Streamlined 500 Questions are designed to help learners save time by eliminating simple common-sense questions, rarely tested questions, and those with obvious answers. Therefore, completing the Streamlined 500 Questions should be sufficient to pass Subject 1. However, individual results may vary, and it's crucial to read each question carefully during the exam. Additional reference materials are as follows: Tips for the Driving Test: Do not cross solid lines or pass over dashed lines, yield more at obstacles. Turn left first, then right, maintain a steady low gear when encountering water, and yield to merging vehicles. Use low gear for sufficient power uphill and to reduce accidents downhill, give way to special vehicles. On the road, watch for markings and signs, move to the right when overtaken. In case of a flat tire, stabilize the steering and brake gently. Do not drive assembled vehicles; doing so will revoke your license. Keep 30 meters away from gas stations and fire hydrants, even when parking. On curves, stay to the right, avoid overtaking and occupying lanes, and park at least 50 meters away. On mountain roads, do not overtake, yield to the side with the cliff. Before crossing water, stop first, then look twice before proceeding. Deer are wild, cows are livestock. Pay attention to yellow road signs indicating children, pedestrians, and bicycles.

What is the reason why the handbrake cannot be released after being pulled too high?

The reason why the handbrake cannot be released after being pulled too high is due to the excessive height at which it was pulled. There are three types of braking systems: Foot Brake: The commonly used brake while driving is operated by the foot, hence it is also called the foot brake. When the driver presses the brake pedal, the braking force is transmitted mechanically or hydraulically to the wheel's braking device, generating friction. Parking Brake: Known as the handbrake, it is a braking device used to prevent the vehicle from slipping when parked. There are generally two types: one installed on the driveshaft (central braking type) and another that directly controls the rear wheel braking. Anti-lock Braking System (ABS): When driving on slippery or icy low-friction roads, excessive braking can cause the wheels to lock up and lose traction, leading to a loss of directional control. To enable effective control of the vehicle's direction on such hazardous roads, the ABS (Anti-lock Braking System) was developed.

How many times can you take the Driving Test (Subject 3) in a month?

Subject 3 (Road Test) is offered twice a month, once at the beginning and once at the end of the month. However, generally, each person can only take it once per month. The comprehensive evaluation criteria for the Subject 3 test typically stipulate that the road driving skills section is scored out of 100 points, with a passing score of 90. Before getting into the vehicle: Regardless of your position relative to the vehicle, always walk around the front of the car from the right side to the driver's door. First, check for any obstacles on the road ahead, then look behind the vehicle for approaching traffic. Ensure it is safe before opening the door and getting in. Adjust the seat, the three rearview mirrors (left, right, and center), and fasten your seatbelt as quickly and proficiently as possible. Observe the dashboard.

Depress the clutch, shift to second gear, and release the clutch slowly while gently pressing the accelerator with your right foot to prevent jerking or stalling.

What is the grace period for car insurance lapse?

There is no specific grace period for car insurance lapse, but it is advisable to renew the insurance as soon as possible before it lapses to avoid affecting the annual vehicle inspection and other protections. Here are 3 key points to consider when purchasing insurance: Avoid duplicate insurance: When purchasing insurance, avoid duplicate coverage. Even if the owner duplicates coverage for a particular type of insurance, they will not receive excess compensation in case of a claim. Avoid over-insurance or under-insurance: Over-insurance or under-insurance does not provide effective coverage. According to Article 39 of the Insurance Law: The sum insured shall not exceed the insured value. If it exceeds the insured value, the excess portion is invalid. If the sum insured is lower than the insured value, unless otherwise stipulated in the contract, the insurer shall bear the liability for compensation in proportion to the ratio of the sum insured to the insured value. Carefully review the insurance documents: Check whether the third copy is printed on white carbonless paper with light brown anti-counterfeiting background patterns, whether the upper left corner is printed with the words "Supervised by the China Insurance Regulatory Commission," and whether the upper right corner is printed with the words "Limited for sale in ×× province, city, or autonomous region."
