I changed the motor mounts and the front flex disc. I removed the trans mount and it looked good so i put it back. The rear flex disc is ok. I did valve a adjustment. So far as i could tell the drive shaft support looked good seemed to me to be solid, but I'm not that farmiliar with this. Tie rods were replaced. I increased the idle speed with the idle screw. still it vibrates like the mounts or trans mount were bad. Could it be something with the Injection pump. ANY HELP AT ALL IS APPRECIATED. RAY M
