About three weeks ago I had a reputable VW Mechanic, Baum's in New
Cumberland PA, put a generic Bosh O2 sensor on my Vanagon (the kind you have
to splice) from Bus Depot. The past two times I have driven in the rain, the
van loses power, stumbles/misses, and eventually sputters out. The weird
thing is, it will start right back up, drive for about 30 seconds, and then
do the same thing. Strange...
