How to adjust the time on a Chery QQ3?

Why does the car sometimes have unstable idling speed that fluctuates up and down?

The reasons for the car's idling speed fluctuating up and down may include: 1. Excessive carbon buildup in the throttle body. 2. Leakage in the intake manifold or various valves. This fault directly affects the quality of the fuel-air mixture and combustion efficiency. Possible leak points include the intake manifold, vacuum hoses, charcoal canister valve, exhaust gas recirculation (EGR) valve, positive crankcase ventilation (PCV) valve, etc., which need to be inspected one by one. 3. Valve timing fault, incorrect valve timing, misaligned timing belt installation, excessive carbon buildup on intake and exhaust valves, broken valve springs, etc. If the intake air volume of each cylinder is inconsistent, it will cause unstable idling. 4. Blocked catalytic converter. A blocked catalytic converter not only causes unstable idling but also leads to insufficient power. 5. Fuel injector faults, such as poor atomization or clogged injectors, which require cleaning. 6. Low fuel pressure. Mainly check whether components like the fuel filter and fuel pump are clogged, or if the fuel pipe is deformed, etc. 7. Engine misfire (missing cylinder).

What to Do When the Car Shakes?

Solutions for car shaking: 1. Severe engine carbon buildup: Clean the fuel system and check if the idle speed motor has carbon buildup that needs cleaning; 2. Ignition system issues: Check if the spark plugs have excessive carbon buildup and replace them if necessary; 3. Unstable oil pressure: Check the oil pressure and replace components if needed; 4. Aging engine components: Inspect promptly. There are two methods for cleaning the throttle body: disassembly cleaning and non-disassembly cleaning. Disassembly cleaning involves removing the throttle body assembly, and the technician uses a specialized cleaning agent to thoroughly clean the internal contaminants before reinstalling it, ensuring a more thorough cleaning effect. Non-disassembly cleaning involves cleaning the throttle body directly with a cleaning agent without removing the assembly, which is less thorough and not as safe.

What is the trunk size of the Tiguan L?

710mm to 820mm is the height of the Tiguan L's trunk, with a minimum width of 1000mm, a maximum width of 1400mm, and a maximum depth of 1940mm. How to open the Tiguan L's trunk: Press the unlock button on the handle inside the driver's door to open the trunk; the vehicle must be parked and turned off for full unlocking, or when the vehicle is locked, press the trunk unlock button on the remote for more than 3 seconds to open the trunk separately. In addition to general cargo loading, the Tiguan L's trunk has several other major functions: When going on a long-distance trip, owners may carry some water in the car, and the built-in hooks in the trunk can be used for this purpose. Or when the owner purchases aquatic products, they can use these hooks to hang the aquatic products, preventing water from spilling into the trunk. If fragile items or items that need to be secured are placed in the car, the trunk's elastic net can be used to fix these items. In case of an emergency, if someone is trapped inside the car, they can use the trunk's escape pull ring to open the trunk and escape.

What gear should an automatic car be parked in?

Automatic cars should be parked in P gear. After the car enters the parking position, follow these steps: press the brake pedal, shift to N gear, engage the handbrake, release the foot brake, turn off the engine, then shift to P gear and remove the key. Automatic transmissions have two gears for parking: P gear and N gear. From a transmission structure perspective, both can be used for long-term parking. P gear stands for Park gear - literally meaning it's designed for parking. Its mechanism involves a ratchet and pawl system that locks the transmission components. N gear is Neutral gear - engaging this gear disconnects power output from the transmission, which can also be used for parking, functioning identically to manual transmission's neutral gear.

What Causes Transmission Oil Leakage?

Transmission oil leakage causes: 1. Poor sealing gaskets in various transmission parts, damaged oil seals or loose fastening bolts, cracked transmission housing, excessive gear oil, clogged transmission vent holes, worn oil seals or flanges, excessive axial end clearance, loose bearing seats and bearings, damaged gaskets; 2. Improper lubricant usage, gaps on sealing surfaces, pressure differentials on both sides of seals. Eliminating or reducing any of these factors can prevent or minimize leakage. The transmission mainly refers to a vehicle's gearbox, which comes in manual and automatic types. Manual transmissions primarily consist of gears and shafts, achieving speed/torque variation through different gear combinations; Automatic transmissions (AT) comprise torque converters, planetary gears, hydraulic torque variation systems and hydraulic control systems, achieving speed/torque variation through hydraulic transmission and gear combinations.
