CEL: How much to fix?

when I said scan tool I was talking a Tech II or something. I need to be able to tell what components are assoicated with that code and to test them individually. I have tested the purge valve and the solenoid valve by giving them gave power and ground at the part and they both work.

That shop is in Rochester I used to work at but they are too busy to mess with this on a saturday.

To the people who understand, thanks. Ill go to a shop soon and see if I can haggle something…

Dawn, get your headlights fixed before you worry about my car. lol
