Engine vibration after changing engine mounts.

If this was not a problem before this was done it brings to my mind they are not adjusted properly. Sometimes it helps to loosen the mounts and pry enginge and transmission around its position to get the mounts centered and out oif a bind. Also I have seen problems with cheaper aftermarket mounts that do not insulate vibration as the orgininal equiped mounts.

agree w/ miles recheck your work and look for motor sagging and touching frame in spots
