This seems to be a common problem on most F22/F23 engines. I assume yours is either a 4th gen or 5th gen Accord. Most of the vibration had been quelled out of the 6th gen, but mine is still noticeable when it's cold outside.

If it really bothers you, you can try different spark plugs that might have the idle a few 100rpms different, which may stop some of the offensive vibrations from hitting the steering wheel.
