That leaves you with the Activated Charcoal Cannister or Shutoff Valve. I'm betting on the Cannister as the most likely culprit, especially on a '98. Hope this helps...

Jim,

Sorry for all the bother but I am travelling in China right now and cannot get pricing on these components. Do you have any idea on the cost of each and the time to repair?

Thanks again,

Tom
