You may have a low speed miss fire or the idle is way to low, start with a tune up first and do a scan to check for any unresolved fault codes, and as a precaution check all engine & transmission mounts, start here.

My car is a 94. Spark plugs, wires are new but they did not solve the problem. Is it possible to visually diagnose if the issue results from mounts? Just by looking at- and if reachable- by feeling them?

You need to place a jack under the sump, use a block of timber so not to do any damage, and take the engine weight slowly, check to See how much movement there is in the mounts.
