What Causes Engine Shaking After Cleaning the Throttle Body?
1 Answers
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.
