The O2 sensor should be replaced ever 80k miles, I doubt you drove your van 80k miles in a year, but I could be wrong. If you want more help I would strongly recommend posting to the vanagon mailing list, send an email describing your problem to vanagon@lenti.med.umn.edu . This is a great source of information,
