Yeah rasmataz I came across the site that listed that information.

What I am really looking for is the most common solution.

I've been looking around the internet for a few hours and made a couple calls.

The most common solution seems to be replacing the purge solenoid.

I'm probably going to do this. I was just looking for some reassurance.

I read that when this device doesn't open it trips the service engine soon light.

I took it off and tried blowing in the holes where the tubes connect to it. I couldn't blow into it. There is no where for the air to go.

I inspected and blew through all the lines. They seem fine.

If replacing the purge solenoid doesn't work what should I try next?

The most common problem when that code comes up is a loose gas cap.
But, if it's a legitmate problem, Id check the vacuum lines in and around the vacuum ball, and the fuel return line.
