It's a '74 2.0 D Jet. On two separate runs (+ or - 200 miles each way), one last fall and then again this week, I have experienced rough running and cutting out. This happened immediately after startup in the morning. It smoothed out in about four or five minutes, but was unsettling as I was 150 miles from home. As it stays in the garage thru the winter, these are the only times I can remember starting it up after it stayed outside in the cold (around freezing). What's going on here? Is there any history of this. Help?!
