What should I do if Honda's idling speed fails in Sundiro?

Yes, the normal idle speed of the engine should be within the 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.

If you can't operate it yourself, it will be safer to go to a professional repair shop or 4S shop for adjustment. Because the early adjustment of automobile idle speed is very important, if it is not done well, the late adjustment will be inaccurate. The preconditions for adjusting idle speed are: normal engine temperature, proper valve clearance, normal ignition system, good sealing of all pipelines, full throttle opening and tight throttle closing.

Extended data

Causes of unstable idle speed

1. Observe the shaking degree of engine cylinder block, and also observe the shaking degree of dipstick handle. The smooth dipstick handle is very clear, and the shaking dipstick handle looks double;

2. Observe or read the data block from the engine tachometer, and the speed fluctuates near the expected idle speed or violently at the expected idle speed side. The expected idle speed in the program includes standard idle speed value and load idle speed value (turning on the light, automatic transmission shifting, etc.). ), air conditioning idle speed value, warm car idle speed value;

3. Start the engine in situ, and sit in the seat and feel the body shaking violently.

4, cold car (coolant temperature below 50℃) rhythm is unstable.
