John,
I have an 85 GL Weekender and had a similar problem. Admittedly, it doesn't
get as cold in Atlanta as Anchorage, but my problem was definitely cold
weather related. My engine would stutter and occasionally cut out
completely in cold weather operation (freezing level and below). It always
restarted immediately. The one time I drove in single-digit temperatures,
the problem was bad.
The problem got worse last winter when the van stranded me a couple of
times. The engine would just quit. One telltale sign was the tachometer
would always drop to zero. Immediate attempts at restarting were futile.
Two local VW shops came up empty, as the engine would always start perfectly
when dead cold. I was finally able to duplicate the problem at a repair
shop. They traced it to faulty Hall Effect sensor on the ignition circuit.
Replacing this component solved my problem.

I am located in Anchorage Alaska, and have an 87 Syncro Westy with a cold.
When the temperature drops into the single digits, the engine hesitates and
stutters. It seems to be worse AFTER the engine warms up, and the problem
intensifies at around 3500 rpm. I have replaced the T2 sensor. I also ran
about four tanks of Chevron Supreme through it, and thought I had it
licked... until the temperature dropped again. The gas up here is
"oxygenated" with ethanol, so we have a built in gas dry supply. This
weekend, the temp dropped below zero and the hesitation returned. Sunday
the temperature was back up into the "balmy teens" and the hesitation quit
again. No problems starting, even at the lowest temperature, and this
without any type of pan heater. Any ideas? I am thinking this is fuel
system related, either the fuel pump or perhaps pressure regulator.
Something that doesn't warm up significantly with the engine. I have tried
searching the archives, but can't zero in on anything that fits. Thanks,
John
