FUEL SMELL, ROUGH IDLE

2003 Lincoln Town Car • 110,000 miles

While stopped at light, heard a loud POP, then the car sounded and ran very rough. Was listening to it today (and recording the sound for reference) and also noticed a fuel smell. The sound is almost like a ticking/clicking sound which increases once the car is put into drive (sitting or moving)

That could be a leaking or bad fuel injector. There are several possibilities though. So, I am giving you a walk through diagnostic for this situation. When you come to the part about, "Trouble Codes", you can get them read at any Advance Auto or Auto Zone for free. They also offer loaner test and specialty tools if the diagnostic calls for them. It would not hurt to test your fuel pressure.
