My FICO score at end of July, 2007 was 681(TU).
I paid off 2 auto loans in first week of August. I then pulled my TU CR in the last week of August, to find my FICO score had plunged to 649. Ugghhhh.
The ONLY other thing that could have effected my score was that I applied for and received a Chevron/Texaco gas card.
Hope that helps.
