P1639 Ford 2002 Mustang GT V8

Question

I have a 2002 Ford Mustang GT and it brought up this code two weeks ago and started choking out. I presumed it was the fuel filter so last week I swapped that out. The service light did not go away. Today I went and got the obd read and it came up with this code (P1639) and another (P1299). I had them reset and on my way home came up again. I don't know what happened or where to go from here. I don't know cars so if anyone can help me I would greatly appreciate it. Thank you.
