Try at least three tankfuls of a Top-Tier gas.

The sulphur is in the fuel.

I don't use "top tier" gas in anything so I doubt that's the problem.
Now I don't know what the problem could be other than a bad catalytic convertor,but the fact that you can smell exhaust fumes inside the van is the biggest cause for concern.

Top Tier gas has more detergents than most gasolines. It could be the solution.

I live in a hilly area, and the cars ahead will often leave a suphur smell. If you notice a pattern, try putting the A/C on Recirculate for a while.
