Unless the motor mounts have been replaced before (certainly possible), I would be amazed if they are in good shape at that vintage and mileage. In our '91 2.3 with 104k mi I performed the 13mm hex bolt test, and they failed. On visual inspection, nothing seemed amiss. Checking at replacement, the unloaded new mounts were only about 1/2" taller than the old, demounted. The engine used to 'bounce' and knock often when starting and transmit a lot of vibration when cold backing out of the garage. Although smooth and quiet cruising along, noise and vibration would increase a smidge when the suspension would compress traversing bumps and dips.

All those conditions disappeared after replacing the two mounts, and the overall low noise and vibration level went down further.
