Question about 1993 Subaru Legacy
If you have the turbo charged version, this issue refers to the "turbo dead zone" between 3500-4000 RPM. This refers to the no acceleration between these two RPMs and is caused by the time difference between the time the second turbo kicks in after the first turbo has activated. If you are referring to acceleration loss/delay below 3500 RPM, the issue is "turbo lag" which pertains to the delay in time between the stepping on the gas pedal and the 1st turbo activating.
In some other instances including non-turbo versions, the problem may be due to air leak in the intake manifold and the air cleaner. In the turbo versions, it would include the in/out junction of the blower including the clamps.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
