If a car runs fine and then starts to run rough, it could indicate several potential issues. Common causes include a faulty spark plug or ignition coil, which can disrupt the engine's firing sequence, or a clogged fuel filter affecting fuel delivery. Additionally, problems with the air intake system, such as a dirty mass air flow sensor, can lead to rough idling. It's advisable to have the vehicle diagnosed by a mechanic to identify the specific issue.

Rough idle runs rough Lincoln town car 1998?
I have 1998 a Lincoln town car with the same problem.. It idles rough when you start, then smooths out once it warms up and you give it gas. From what I am reading its either an oxygen sensor or you have vacume leak in one of your hoses by the manifold.

hard to say but if it runs rough & this is related you may have a leaking intake manifold or head gasket causing vacuum loss (reason for rough idle) & leaking out the antifreeze - both are expensive to repair
