What Causes Intermittent Engine Shaking When the Car Air Conditioner is On?
1 Answers
Intermittent engine shaking when the car air conditioner is on is generally caused by a dirty throttle body, which affects the engine. Below are specific details about a dirty throttle body: 1. When the air conditioner is turned on, the compressor also operates. Since the compressor is driven by the engine, its operation increases the engine's load. This increased load requires a greater throttle opening, leading to more air intake. If the throttle body is not maintained for a long time, carbon deposits can easily accumulate. These deposits obstruct the engine's air intake, making it difficult for the engine to drive the compressor adequately, resulting in idle shaking. 2. The throttle body needs to be cleaned. If the driving environment is harsh, it is advisable to clean it regularly—recommended every 10,000 kilometers.
