What should a Honda Accord idle at?
Typically, the idle speed will be set at a value in the range of 600 to 800 RPM, but the exact value will depend on the number of engine cylinders and whether the vehicle is equipped with a manual or automatic transmission.
What should the idle speed be on a Honda Accord?
Your Accord’s engine should be at a constant low idle when parked and should not be revving or fluctuating. Having an idle problem is always something you want to take care of as soon as possible.
What does fast idle thermo valve do on Honda Accord?
The fast idle thermo valve (FITV) controls the idle at cold starts. It keeps the idle high and gradually decreases the idle as the car warms up. These three parts should be taken out and cleaned. If they are beyond cleaning and repair, they should be replaced.
Why does my Honda Accord vibrate when I idle?
When the spark plugs wear-out or are faulty, the engine misfires and some cylinders fail to fire effectively, resulting in the vibration. Faulty spark plugs cause the Honda Accord to rough idle and vibrate abnormally when it’s still. The solution here is to replace the worn out spark plugs with new ones.

Why does my Honda Accord feel like its down a cylinder?
Fouled or otherwise dead spark plugs will make the car feel like it’s down a cylinder or two (and it may be!) and will cause excessive vibration for the engine when running poorly. Pull all four spark plugs and inspect for damage or corrosion. Figure 3. Reading spark plug conditions.
