Service engine light on. Showing code p0171 "running lean on bank 1" I replaced

Checked the mass air flow sensor. It was clean, but removed it and cleaned it with air flow cleaner anyway. I inspected the exhaust more closely and noticed a broken stud and pretty good air leak on the flange between the upper sensor and the cat. The leak is about 2 inches from the upper oxy sensor. Will the leak trip the p0171 code??
