      I have a 1997 honda accord and when my car is at idle, it shakes and vibrates. The Rpms are fine and the car runs like a champ. I can’t seem to find out why it vibrates at idle. Any ideas?

        Also when I go over bumps I always hear this clunking noise. My guess is maybe I have a motor mount issue. Lead me in the right direction please.

          I vote for bad motor mount. Also check your shocks and struts. http://www.youtube.com/watch?v=80C2N9ecSj4

            A+ on the above post. as for the engine shake at idle. you either have a miss fire which I would do a power balance test to isolate the problem cylinder.
            also check for vacuum leaks. Eric’s videos show both of these practices good luck and keep us posted. C8-).

              Here is a link to Eric’s idle speech and video’s –

              It wouldn’t hurt either to do a solid visual of the motor mounts as suggested.

              Any CEL?

                You’re my man Dreamer, remember that the mounts are LAST on the list after addressing all the other issues but a good visual can’t hurt.

                    The first thing to check for clunking in the front end of a Honda is for missing fasteners on the splash shield.

                      A compression test is cheaper than motor mounts…

                        I would check the engine mounts. Also clean the throttle body if car has more than 100K miles. The clunking noise, where is it coming from? go find a speed bump and slowly drive it over at different angle – find the source of that noise. I am suspecting sway bar end links – which is very common problem for Honda.

                          Does the car shakes when you are in reverse? If yes then the front torque mount is totally gone. Are you the original owner of the car? If the car does not shake in reverse, and only shake in neutral or idle, and you are not the original owner, look at the front torque mount. It might be the last owner replace it with a polyurethane mount, which is much stiffer and cause the car to shake a little more at idle as mine is. However, more torque goes to the ground and the gas pedal is a little more responsive.
                          If engine mounts are bad the clunking sound are usually cause by the 2 side ones. The shakes is more of the front and rear.
                          With all that and I forgot to ask you what kind of shake is it? Is it really bad? As intolerable or just minor shakes?
                          Good luck.
