Reasons for Changan Eado's Idle Speed Fluctuating and Stalling
1 Answers
Reasons for Changan Eado's idle speed fluctuating and stalling are as follows: 1. Sludge: Dirt from the air and sludge from gasoline can easily cause the throttle valve to become dirty, leading to poor operation of the idle speed control valve. 2. Carbon deposits: Excessive carbon deposits can cause the valves to not close tightly, poor fuel injector atomization, and insufficient combustion. 3. Blockage: A blocked exhaust pipe can lead to poor exhaust flow. 4. Air leakage: Air leakage results in insufficient vacuum. 5. Aging wiring: Aging wiring or issues with the ECU (computer board), though this phenomenon is unlikely to occur in the short term. It is recommended that owners avoid installing additional devices on the vehicle. 6. Insufficient cylinder pressure: Natural wear leading to insufficient cylinder pressure, though this phenomenon is also unlikely to occur in the short term.
