End of an Oil Pump?

I have a 1991 Chevy Astro Van that I purchased new; it has 100,000 miles on it. I have taken extremely good care of it and have had no serious problems at all, just routine maintenance. However, I have recently noticed something that concerns me. My oil pressure gauge is showing that I am not holding a constant pressure. At first when idling it would run very low and when cruising at various speeds it would run high. At that point I replaced the oil pressure sensor and it no longer indicated high pressure when running. It appears normal at cruising speed now. My problem is when I need to stop and the engine idles. The oil pressure gauge shows a low pressure reading and there is a slight indication that the engine is not running at its normal idle speed. I have had no problems but this does not seem right. I change my oil and filter regularly but the pressure continues to run low when at an idle. Could the timing be off? Do I need to replace the oil pump?
Well, if the engine is operating normally and it is at the correct idle speed, then I would think that either the oil pump is getting tired, or there may be a plugged journal somewhere. That motor may have an external oil pump, so it may not be so bad to change it.
