1992 Mercury Capri XR2 Convertible 2-Door 1.6L

This is a very nice mercury Capri. I have had for about four years and I have put very few miles on it myself it spent most of its time in garage in storage There is no rust and tires are in very good shape the car drives and handles excellent. But when it sets for a period of time it runs rough until it warms up It is possible the valve guide seals dried up and now lead because of a long time of setting a very simple repair. ny questions please feel free to ask thanks,
