My 1998 mustang has a vibration between 40 and 55 mph only when I am slightly on the gas pedal, its a very noticeable shake. It feels and sounds like it is right underneath me, It also seems to happen when the car reaches operating temperature. engine runs good, plugs and wires are good, no check engine light. any ideas?
