KIA Spectra Problems

I had my engine light come on and the dealer said I need to change the purge valve on a 2003 KIA spectra. Any advice? How to do it? How much it should cost?

Hi there - I am a newbie - Our engine light came on right at 60 000 miles.....
I am not ready to go to the Dealer......
What should we do?

I know it's an older post but I just wanted to mention there's a recall for that. And you don't have to pay anything for it. http://www.obd-codes.com/tsb/2003/kia/spectra/
