What is the solution for Honda Accord idle shaking?
2 Answers
Check the working condition of the spark plugs, high-voltage wires, and ignition coils to see if there is excessive carbon buildup on the spark plugs. If so, clean or replace the spark plugs immediately. Clean the vehicle's "throttle body" right away. If this does not resolve the issue, the car must be sent for repair. Clean the fuel system and check whether the idle motor has carbon buildup—it should be cleaned thoroughly. Check the fuel pressure and replace components if necessary.
I once encountered an idling vibration issue with my Honda Accord. The car shook noticeably at red lights, and I could even feel the steering wheel trembling. First, I checked the spark plugs – if they're worn out and don't ignite strongly, it can affect idle stability. I also removed and cleaned the throttle body of dirt, as buildup can restrict airflow and cause shaking. Additionally, clogged fuel injectors might lead to uneven fuel supply and require cleaning. If these simple steps don't work, I'd recommend inspecting the engine mounts. Worn mounts transmit too much vibration, and replacing them can make a big difference. Idling vibration isn't just bad for fuel efficiency – it's dangerous too, as it can distract you and lead to accidents. That's why I addressed the problem immediately, and the car ran much smoother afterward. Regular maintenance is crucial; for example, cleaning the throttle body every 20,000 kilometers can prevent many issues.
