After adjusting the valve, the seventh-generation Accord will stall at idle speed.

Does the subject want to ask, "What is the idling after the seventh-generation Accord has adjusted its valves?" Idle speed control system failure and ignition system failure.

1. Idle speed control system failure: The idle speed control system of the seventh Accord includes idle speed control valve, throttle sensor, temperature sensor, etc. If these sensors fail, it will lead to unstable idle speed or even flameout, so it is necessary to check, repair or replace the failed idle speed control system components.

2. Ignition system failure: The ignition system includes ignition coil, spark plug and other components. Ignition system failure will affect combustion efficiency, leading to engine instability, unstable idle speed, and even flameout. It is necessary to inspect and repair or replace faulty ignition system components.
