The Rack Damper bolt is adjusted all of the way in at this time. It is the old bolt so I was looking at upgrading to the new bolt (its longer, i guess). I can almost bet that the old one is worn.

The shakes are only really apparent at low idle after the engine has warmed up some (mainly when I am stopped at a signal). The shakes happen most of the time, but not all of the time (even on the same drive). If I give the engine just a touch of fuel with the pedal, the shakes minimize considerably.

The Engine mounts and engine shock mounts are new. (w/i the last 6 months)

I am planning to change out the fuel filter, inline fuel filter, and hand primer pump tomorrow to see if it has any effect (its been 5000 miles since i changed them).

Any other observations would be helpful and appreciated.
