What causes the car to jerk when reversing?

When the car jerks while driving, it is usually due to an issue with the ignition system, commonly caused by faults in the spark plugs, ignition wires, or ignition coils, which require self-inspection. Below is relevant information: 1. Worn spark plugs: This jerking phenomenon while driving is referred to as hesitation during acceleration. The most common fault is damaged spark plugs. Due to wear on the spark plug electrode gap, the spark plug's ignition capacity decreases, preventing the air-fuel mixture from burning completely, thus causing the jerking. 2. Poor fuel quality: Additionally, if the car uses low-quality gasoline, it can lead to poor atomization in the fuel injectors. The air-fuel mixture cannot burn completely in the cylinders, resulting in idle jerking. If the issue is due to fuel quality, a fuel system cleaning can be performed, followed by the use of higher-grade gasoline.

How Many Attempts Are Allowed for Subject Two and Subject Three?

Subject Two and Subject Three can each be scheduled for a maximum of five attempts. If either Subject Two or Subject Three exceeds five scheduled attempts, you will no longer be able to book the exam, and all previously passed subjects will be invalidated, requiring you to re-enroll and start over. Below is relevant information about Subject Two and Subject Three: Pros and Cons of Taking Subject Two and Subject Three Consecutively: 1. "Pros" in terms of time-saving: After passing both Subject Two and Subject Three consecutively, some regions allow you to proceed directly to Subject Four and obtain your license on the same day, significantly reducing the time cost of learning to drive. 2. "Cons" in terms of tight scheduling: The psychological pressure of rushing between exams is high, and the different rhythms of Subject Two and Subject Three may affect exam performance, but these are not major issues.

How to Perform Keyless Entry Key Fob Retrieval?

When a keyless entry key fob fails, it's usually due to a dead battery or system malfunction. The specific situations and solutions are as follows: 1. Dead key fob battery: The key fob contains an internal battery; if the battery is dead, the key won't function. The solution is to replace it with a new battery. 2. Dead vehicle sensor battery: If the vehicle's sensor battery is dead, even with a functional key fob, the two won't connect. The solution is to replace or recharge the vehicle's battery. 3. Mechanical or system failure: If both the key fob and vehicle sensor have power but still won't connect, there may be a program or mechanical issue. In such cases, visit a 4S shop or repair facility for further diagnosis.

What is the optimal tire pressure for fuel efficiency?

The standard air pressure for passenger cars is 2.4-2.8 kg/cm². Excessive tire pressure reduces the contact area between the tire and the ground, dramatically increasing the pressure and wear per unit area, which can easily lead to braking failure. When encountering road protrusions or depressions, it may cause tire blowouts and damage the vehicle's suspension system. Relevant information about tire pressure is as follows: 1. Introduction: Strictly speaking, tire pressure refers to the air pressure inside the tire. In automotive maintenance, the engine is considered the heart of the car - engine failure means the end of the vehicle's life, while tire pressure acts as the car's blood pressure. The level of tire pressure plays a crucial role in the vehicle's performance and power. 2. Hazards of excessive tire pressure: It reduces tire friction and adhesion, affecting braking effectiveness; causes steering wheel vibration and deviation, lowering driving comfort.

What causes the EPC warning light to illuminate and the inability to accelerate in an old Jetta?

The reasons for the EPC warning light illuminating in an old Jetta are as follows: Intake system malfunction: Such as leaks or blockages. Troubleshoot intake system issues, use compliant fuel, clean the throttle body, etc. Throttle body contamination: Dirty throttle body or excessive carbon buildup. Remove carbon deposits from relevant components. ECU malfunction: Re-flash ECU-related data. This method is used when other faults cannot be resolved. Engine management system malfunction: This condition is often accompanied by unstable idle speed and engine cold start vibrations. It is mostly caused by poor fuel quality and dirty driving environments in the country. In such cases, the vehicle should be immediately taken to a repair shop for inspection and servicing.
