I have an occasional excessive engine shake at idle. It does not happen all the time but usually occurs when the engine is warmed up...and most often just after I have exited from the interstate (70-75 mph) and stop at the light off the exit ramp. I have read allot of posts regarding excessive engine shake and I am leaning towards the rack damper. However, could be the engine shocks?

Overall, the engine has good power, no smoke, and other than this infrequent issue appears to be quite strong.

Any advice?
