How to adjust the idle speed in Wuling Glory?

You can refer to the following methods:

1. First, loosen the throttle opening adjustment screw to make the engine reach the lowest stable speed.

2. Screw in the idle speed adjusting screw with a screwdriver, and then slowly unscrew the idle speed adjusting screw when the engine is about to stall, so that the engine can run smoothly and reach a high speed. Then loosen the throttle opening adjustment screw to make the engine speed as low as possible. Then adjust the idle adjustment screw to increase the engine speed. Repeat this process until the throttle opening is minimum and the engine runs at the lowest stable speed.

3. Finally, increase the speed and suddenly close the throttle, so that the engine can still turn without stalling.

Idle speed adjustment must be carried out under normal conditions, such as normal engine temperature, proper valve clearance, normal ignition system, good sealing of all pipelines, full throttle opening and tight throttle closing.

Glory idle speed is high, generally for the following reasons:

1. Idle switch is not turned off.

Diagnostic method: Turn on the air conditioner and turn the steering wheel when idling. The engine speed does not increase, which can prove this fault.

Troubleshooting: Adjust, repair or replace the throttle position sensor.

2. Idle speed control valve (ISC) is faulty.

Diagnostic method: Check the starting sound of the idle control valve. If there is no starting sound, the idle control valve is faulty.

Troubleshooting: Clean or replace the idle speed control valve, and set the idle speed with a special decoder.

3. The air inlet pipe leaks.

Diagnosis method: If you hear the smell of air leakage in the intake pipe, it proves that the air intake system is leaking.

Troubleshooting: Find the leakage, reseal or replace the phase parts.

4. The oil supply system is too dirty

Diagnosis: If the engine shuts down at low speed, it must be an oil circuit problem.

Troubleshooting: Clean up the carbon deposit in the oil supply system and spark plug.

Extended data:

Discrimination of poor idle speed;

The normal working engine should be able to run evenly in the speed range of 300-500 rpm. If the lowest stable speed of the engine exceeds this speed range, or the engine flameout and unstable speed occur within this speed range, there is no idle speed or poor idle speed. When the idle speed is poor, it can be divided into idle flameout, unstable idle speed and excessive idle speed according to its fault characteristics.

If the engine runs well from low speed to high speed after starting, but turns off immediately after releasing the accelerator pedal, or turns off after unstable operation, it belongs to idle flameout fault. If the engine is not running smoothly at idle speed, the exhaust pipe makes a "chug chug" sound, which is generally a fault of unstable idle speed. If the lowest stable speed of the engine is higher than the specified range, and the speed cannot be reduced, it is considered that the idle speed is too high or there is no idle speed fault.
