Low idle HELP!!!!!

[chrischiou]

So I was driving my car today and suddenly the tach starts to bounce around. It will drop down to bout 500rpm till the point it is about to stall and shake then it will bounce back to bout 800. It's been doing this all day and it's starting to worry me. Can someone please help me!!!
