When I bought my 1991 Volkswagen Vanagon GL Campmobile with 2.1 waterboxer,
it had severe hiccups, which were intermittent and hadn't shown up in my
test drives or to the mechanic who inspected it for me.  When the hiccups
did show up, I took it to a good Vanagon mechanic.  He did all the standard
tune up procedures, plus grounds, connections, AFM replacement (not that
expensive).  In the 50K miles I've driven it, it has never hiccuped.
Solid, standard maintenance works wonders.
