What is the solution for low idle speed in Honda CRV?

[AliceAnn]

Below are detailed explanations regarding the causes and solutions for low idle speed in Honda CRV: 1. Severe engine carbon deposits: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the cold start injector can be largely absorbed by the carbon deposits, resulting in an overly lean mixture during cold starts and making it difficult to start. In this situation, the engine will only start easily once the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits will be drawn into the combustion chamber by the engine's vacuum suction, making the mixture too rich. The fluctuating mixture of lean and rich conditions causes idle speed fluctuations after a cold start. 2. Ignition system issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or weak spark plug firing can also lead to such faults. Inspect the spark plugs and replace them if necessary.
