I have been driving around ('84 Waterboxer 1.9) in the soaking-wet
conditions here in the Willamette Valley in Oregon, and have noticed that on
wet mornings the engine stutters at low rpm until it is completely warm.
This never happened at home, where it's dry - even when the temperature got
down around 10 degrees Fahrenheit.  �So I don't think it's the cold, it's
the wet weather.  Is this a typical symptom in wet weather, or is it time
for a more general checkup?
