I am trying to narrow the choices of where to look for some really odd vibrations coming from my 84 300D and I thought I would enlist your collective help.
At idle (750 +/-) the engine is a bit shaky - BUT when the A/C compressor engages the car really starts to do a jig. It feels like the car is gyrating from under the front seats and she moves a bit up and down in a circular motion. Smoothes out to it regular idle shake when the A/C compressor disengages. Ideas?????
