Okay, I tried to live with it and I can't. I hear the rear motor mount has some sort of vacuum line to control the motor mount. In checking this out, I found a control mounted to the firewall that sent vacuum to a module that appeared to be connected near this motor mount. The control had an electrical connection and an adjustable knob. (tried the knob and did nothing.) Is this for real and how does this work? Any help would be greatly appreciated cause I can't stand the shake NO MO!!
