Idle problems are often mixture problems. Looking for vacuum leaks was a good start but is the idle RPM where it’s suppose to be? If not you may need to raise it up. Look to the motor mounts last, see what you can do to solve the engine performance issue first. Motor mounts would only be a band aid if the problem is really how the engine is running. Also don’t forget about your tune up items, if they’re old you might want to change them.
