I have just started driveing a 1992 stanza automatic. My problem is when the car is first started up the front dashboard along with the front of the car vibrates pretty good and it is quite loud. The sound disappears as you drive down the road immediately. It only seems to be loud as it is stationary. What is most likely the cause of these vibrations i was told it could be motor mounts but i have also seen there are engine mounts and transmission mounts? Which one of these would be the most likely cause of all this rattleing of the engine and front end. Where would it be located. Also would this be a hard do it yourself job.
