2003 Lincoln Town Car Repair Question
Fuel smell, rough idle
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.
