Shakes or Wobbles problem
1991 Geo Metro Front Wheel Drive Manual 29000 miles

I just Bought a 91 geo metro from a shady guy on Craigslist. The car does fine when idling then shakes when I start to accelerate then is fine again as soon as I get it past the initial start. It isn't the wheels as it still happens when I'm parked and revving the engine. It doesn't appear to be causing any problems as of yet but I would like to stop it before it does. Any information on what it could be would be helpful.
