I had the same problem a few years back...don't lube it, it's bad capacitors. You need to remove the instrument cluster (2 screws behind the two black square on the right and 2 behind the headlight switch cover-pull off the dimmer and headlight nob and use a flathead screwdriver to pop of the template on the left and right of the cluster. Remove the felt paneling on the bottom of the dash and reach up and unscrew the speedo cable--you might be able to get it from up top by pulling the cluster out first. Unplug the two wiring harnesses...slide the cluster out sideways between the dash and steering wheel. Unscrew the screws around the perimeter of the clock back and pull it out. To replace the capacitors, follow the instructions on my post in the archives (it's really pretty easy). If you don't want to fix the clock, you could get a big tach from ebay or a junk yard and just plug it into the back of the cluster where the clock was--your car's pre wired...there's a white wire with a red stripe down the side that you plug into the back of the tach and you'll have a tach.
