LATEST UPDATE FROM DEALERSHIP:
just talked to ford, supposedly, the backfiring was caused by a spark plug that had a "hairline crack" and that they replaced all 8 of the spark plugs yet they are not covered under any kind of warranty. However, when they replaced a coil pack about a month ago, they also replaced the spark plug which WAS covered under warranty...... im confused! They are going to do a test drive after it sits all night to see if the backfiring is still there.
To me, if it was a spark plug that had a hairline crack, it would do it warm and cold, but what do I know? Im just the customer.

according to the advisor, they called ford again on it and "FORD" says that they have heard of it before and was similar to the symptoms I was having. Now they also supposedly talked to ford the last time and was told it was the MAF sensor which turned out NOT to be the problem yet they charged me for it. Granted, it was only a $100 deductible but still, it was something that was not the problem.

So how did the plug crack ? Either it got by QC at the manufacturer or it happened during the install.
