Thanks for the tip - Did you find the proceedure in their Repair Manual or one of the specialty manuals? Buying the book is a great idea. I have the knowledge and all the tools to do the testing my self, and at $100 per hour at the dealership, it's well worth the cost.

Thanks

PS - I replaced the Vent Valve on top of the Charcoal Canister because I saw several posts saying that was a common error. Worked for 3 days, but the light came back on this morning. The posts talk about a CVS - Would that be the Vent valve I replaced?
