Thanks again - my mind is at ease a bit now. It really sucks having the car shut off while moving - seems like a common occurrence when I was kid - but today driving is that much more intense and the people behind you are that much more impatient (plus I didn't grow up around New York). I'll get on those filters.

The Diesel Purge was to help treat a smoking at cold start issue and just general maintenance since I just got the car.
