I have searched and cannot get an answer. I have a 2004 Montero Limited with 120K miles that has an engine vibration at 2200-2400RPM. It does it in every gear including park and neutral(no it is not torque converter shudder). I have read that Mitsubishi has told some people that it is "normal", but that is a load of crap since many people report this issue suddenly appearing. It appears several people have this problem with the gas 3.5L and 3.8L. Just checking to if anyone knows of the solution to this issue. I found a thread where someone basically replaced everything moving and never solved the issue, ended up selling it. This is very annoying since I love everything else about this vehicle.
