I am currently experiencing a high idle problem with my car..... took it to the dealer today and they said it was the IAC......

I was planning on attending at the AutoX at wentzville on sun.... what if any damage could I do to my car if the IAC is not fixed??
Is this something I could do myself? If so where would i get the parts? other than the dealer.?
