What are the causes of high idle speed in Wuling Rongguang?

[NorahLee]

Wuling Rongguang high idle speed causes are as follows: Throttle failure: Leads to excessive air intake, check if the throttle plate is stuck by foreign objects and clean the throttle body, check if the throttle cable is rusted or stuck, check if the idle air control valve passage is normal. Intake manifold causing air leaks: Check if the intake manifold is damaged, check if the fuel injector sealing rings are intact, retrieve data streams from various sensors, most importantly check if the intake pressure is normal. Other conditions: When engine coolant temperature is low, air conditioning is on, or engine voltage is low, the ECU programming will appropriately increase idle speed - this is normal. If the engine coolant temperature is normal, air conditioning is off, yet idle speed remains high, this indicates a system malfunction which could be either electronic control system or mechanical system failure.
