All;

Any idea what could be causing my Cali-spec 1985 300TD to not want to shut off when the ambient temperature is 40 or below? At temperatures above that, shutoff occurs immediately as the key is turned, but if it is cold outside, the car will run on for 30 seconds or more, with the revs slowing and finally stopping.

Haven't had a chance to put a Mity-Vac on it yet, likely that will be this weekend's project, but I can't imagine what in the system could be affected by temperature...

Thanks in advance
