Your Nissan may just idle high during the warm up of your engine. These cars are designed to do this based upon the fact the cars have an optimum running temperature. If they idle high when for the first 15 minuets it's to achieve that optimum running temp. If not then you may have a vacuum leak.

An idle set too high can cause a 1994 Nissan Pathfinder to run at a high RPM in 5th gear. A bad transmission gasket can also cause this.
bad light switch.
