ThirdeYe,
Many Honda/Acura vehicles have had steering wheel vibration while idling. Of course this vibration is usually with an automatic tranny and while in gear at a stop with your foot on the brake. Years ago there were some TSB on these issues. The worst vibrations that I have ever felt in Hondas was on the mid '80's Accord automatics. Some of these cars vibrations were actually violent. Even vibrated the dash and seats. Some of the TSB addressed the issue but most were unsuccessful. The TSB called for a revised rear motor mount and a steering clip on the steering shaft to help control the vibrations along with a slight idle adjustment/tweek.
