What Causes Idle Shaking in Automatic Transmission Vehicles?
1 Answers
Automatic transmission vehicles may experience idle shaking due to the following reasons: 1. Dirty Air Filter: The air filter is designed to protect the engine and reduce wear, typically requiring replacement every 10,000 kilometers. If not replaced in time, insufficient air intake can cause low idle speed, leading to engine shaking. Simply replacing the filter can resolve this issue. 2. High-Voltage Wire Breakage: A break in the high-voltage wire's core can affect ignition and cause engine shaking. Use a multimeter to measure resistance and replace the wire with significantly higher resistance. 3. Spark Plug Lifespan: Spark plugs have a limited lifespan. After 30,000 to 40,000 kilometers, their ignition efficiency significantly decreases, which can affect ignition. This is a common issue that can be resolved by replacing all spark plugs.
