When at a stand still car idles evenly although maybe a bit high (1000rpm), if i was to stop on the top of a hill then just free wheel down out of gear then the rpm's fluctuate between 1000 and 1500 rpm...

Yes. The engine relies on the right amount of back pressure from the exhaust system. If not enough,usually aroung 1.5 psi, then it can cause engine concerns.Check for any and all vaccum leaks first before condeming the exhaust system. Use your ear to locate any large leaks and you can use water to locate any smaller leaks. Listen for a hissing type sound.Check for broken or missing vaccum lines also.The water will be sucked into the engine causing it to decrease the rpm.The idle air control valve would be another part that will cause this concern,but not likely on this vehicle.Hope this helps,
