I have an 89 Spur that starts and runs great when cold. If I drive the car for a bit and then turn off the engine and wait 15 minutes or so and I try to restart it I have to crank the car a good couple of minutes to get the car to restart. Also, it runs rough like a miss for a couple of seconds but then smooths out and runs perfect. The problem is not spark. Does anyone know of a fix gor this? Thanks. Regards, Joe.
