94 VAN DOESN'T IDLE PROPERLY SINCE THE TUNE UP?

1994 GMC Safari

It appeared to have no power when I stepped on th gas, and felt like it was going to stall, so I had a tune up done, plugs, wires, d-cap, rotor and air filter.
Well since the tune up, it idles like crap, it feels like its going to stall but it doesn't. When its turned on and I am just at a light or something it kind of moves back and forth like a freek'n hotrod that wants to go. Does anyone know why it's doing this? I was told to maybe have a cam sink done. WHAT IS THAT?
