hey 2000prelude....... well the front mount had a crack in the rubber, i replaced it, and it made the shaking go away drastically......... hopefully thats what your problem is also.... check out the rear mount even though its hard to see...... also..... when you let it sit and idle and it is shaking.... feel the front bumper and see if it is vibrating/shaking, if so than it is most likely your front mount, even so the engine will vibrate/shake a little at idle, you shouldnt feel it on the body panels/steering wheel because the rubber in the mounts soak up the vibration..... it took away MOST of the shaking/vibration..... there is a TINY bit left now but i think that is normal especially when you turn the wheel cause of the power steering etc... and its probably also because now im looking for ANY sort of vibration or shaking but it was drastically improved because the rubber on the mount was cracked........also, I have a question for you..... when your car is warm and it is idling.... what does it idle at? or should I say how many bars below 1,000 rpms does it sit, because I cannot figure out if the second big bar after 0 is worth 500rpms or if it is still 0........ one last thing......I could not see the rubber broken when inspecting the mount from the outside, it was after I took the mount off that I saw the rubber cracked in the middle, it also makes the car accelerate a little bit smoother. If you are going to do it yourself.... take off the fan in front of the mount and it should be no problem, and if you have a jack then jack up the motor a little bit and have a 17MM wrench for the bolts.....
