Update:
Here in Phoenix, AZ the morning temperatures have been in the upper 40s when I start my car in the morning. I had very rough, sputtering starts before I fixed this exhaust leak. Since fixing the leak, my car starts up like normal - no sputtering at all!
Also I've put about 110 miles on the car and numerous restarts since fixing the leak. Data logging shows my AFR@~12.5 and my LTFT are rock solid @ 0.00 when pulling at WOT.
