1999 ford windstar instruments panel freaking out sometimes and rough idleing?

By freaking out do you mean some of the gauges read inaccurately at times, the dash lights flicker, or the dash warning lights intermittently come on/go off? That could be something as simple as a defective or corroded fuse or relay, loose wiring harness at back of gauge cluster, a loose or corroded battery cable, or a bad gauge cluster.Rough idling can be caused by a weak fuel pump, vacuum leak, dirty egr valve or dirty iac valve, bad pcv valve or clogged pcv valve hose, or dirty maf sensor. If the gauge problem and rough idle problem are both caused by the same thing, a loose or corroded battery cable, battery low on charge, loose or corroded secondary ground(between engine block or head and firewall)defective alternator are a few of the things that can cause this type of problem. You should post another question or list more info under the comment section that describes your gauge issue in more detail because many different problems can occur at the instrument panel.
