The reason for engine shaking after cleaning the throttle body is the lack of data matching. Below are the specific causes and solutions for engine shaking: 1. Carbon deposits in the car causing difficulty in ignition. At idle, it may also be accompanied by slight shaking; cleaning the throttle body and fuel injectors can resolve this. 2. Weak ignition energy from the spark plugs. If spark plugs are not replaced after the maintenance cycle, their ignition energy decreases severely, leading to misfires. 3. Insufficient fuel pressure in the low-pressure fuel circuit. Low fuel pressure directly causes the engine to misfire; specifically check the fuel pressure regulator, fuel pump, fuel filter, and internal fuel lines. 4. Weak battery. Jump-starting the car or using another battery can solve this issue. 5. Incorrect engine timing. Mismatched engine timing or skipping teeth when replacing the alternator belt in certain engine models can cause difficulty in ignition.

How often should the Envision's intake tract be cleaned?

The Envision's intake tract cleaning interval can be every six months or 20,000 kilometers. If there is accumulated debris on the throttle body, cleaning should be performed as needed. Every six months or 20,000 kilometers: Cleaning the intake system every six months or 20,000 kilometers is standard practice. The engine's intake system serves as the gateway for air entering the combustion chamber. Due to the engine's operating environment and airborne impurities being drawn into the intake system for combustion, carbon buildup becomes a primary concern. Throttle body with accumulated debris: If the vehicle operates in highly polluted environments (primarily referring to inhalable particulate matter), debris can quickly accumulate on the throttle body. Over time, this affects engine intake, necessitating cleaning. This issue is most noticeable when starting the vehicle. Depends on circumstances: The cleaning frequency depends on various factors, such as the vehicle's driving environment and the fuel injection system's adjustment method.

Why does the Audi A6 shake after replacing the spark plugs?

Audi A6 shakes after replacing the spark plugs because the cylinder wires were broken or not completely disconnected when removing the spark plugs, causing abnormal ignition; incorrect spark plug installation, such as not tightening properly (threads not aligned) or cylinder wires not inserted properly; cylinder wires not matched to the corresponding cylinders. If the issue is not with the spark plugs, it may be due to aging ignition coils leading to decreased performance. Related information: For the engine to function properly, continuous ignition and fuel injection are required, meaning the fuel injector sprays fuel each time the spark plug ignites. If the spark plug fails to ignite, the cylinder will lack fire when the valve closes, preventing the gasoline from igniting and causing the engine to stall. Methods to determine if the issue is with the spark plugs: When spark plugs malfunction, the engine will continuously shake, especially when the vehicle is moving or accelerating. If there is no shaking while driving, it is usually not a spark plug issue. Testing by revving the engine while stationary can also help diagnose the problem.
