My 1987 Wolfsburg weekender has started to smell like sulfur
 in the passenger area when I accelerate.
I got a new battery yesterday because I thought It was causing the smell.
The battery tech says not.  He says its the emission control on the engine.
If this is true, is it bad for the van?
Shall I be saving up for another catalytic converter?

Thanks,
