Like a lot of members here, I have had problems starting my car when very cold outside or rainy weather but no problem when dry and warm. Yesterday I bought some Seafoam and put it in the gas tank. Drove it around for 20min. This morning, was 35 degrees and pouring. Car started on first crank. This hasn't happened once with the rain or cold weather here in So. Cal. So, I figured at night, after sitting all day, if it does start right away again, I would post this question to the forum. It did! So, has the Seafoam done something to help clean out something or give me better ignition somehow? I did not put anything into the oil or the manifold like it recommends (I didn't know you could do this yet). Does this indicate another potential issue with this '91 300E?

Thanks.....Steve
