Okay I have done some research and I would like an opinion on what to do next. At the NEgtg I noticed that some of the other 123's idled smoother than mine, specifically my aircleaner jumps all over the place while idling in park. The engine (idling in park) however appears very smooth and is to the touch also. Inside the car while idling in park it is very smooth as well, just the aircleaner doing its dance under the hood. The metal aircleaner mount is new but I reused the rubber isolators as they looked fine. Holson Adi suggested I replace them as well as he had a similar problem that went away with new isolators (thanks Holson). Everything changes when I put it in gear though. There is a fair amount of engine vibration when idling in gear, D or R. Sort of a "rump-rump-rump" panzer tank quality to the vibration. There is no vibration at all above idle, accelerating or at cruise speeds. I am inclined to think the motor/trans mounts need to be replaced and I will do the rubber aircleaner isolators while I am at it since they are so cheap. Sound like I am on the right track here? I am tempted to adjust the rack damper bolt but I think that maybe should be left as a last resort? Any input appreciated. Thanks, RT
