I had the same problem (or is it really a solution) with my LX with a slow aperture actuator, probably caused by old lubricant. The aperture was slow in closing down and so more light reached the film so the LX ended the exposure early. If in manual mode I got overexposure, but Auto was fine.
How do you know the speed was 1/1000th rather than 1/350th? I would think they sound the same. In my case I noticed it because I was working at slower speeds.

Post shot shutter speeds: LX 1/1000 and MZ-S 1/350. Time span between shots just moments. Sun movement or clouds (none) not considered factors. I realize that the actual LX exposure/shutter likely varied from pre-exposure reading, but I'm surprised at how much. Perhaps I'm just the last to discover this.
