I don't know if your engine is a 5.4 but the check engine light was on on an expediation which is a same motor if yours is a 5.4 and it needed intake gaskets take it to an auto zone and have them put it on a tester but also I had to put in new spark plugs, air filter, fuel filter, and one of those special plug socket on the number one cylinder be sure to put in double platium plugs

00 lincon navigator 5.4 oil pressure drop's low and light comes on , engine idles rough when pressure drops ,then pressure return s to normal range ,light goes out ,engine runs perfect. Is it my oil


Sounds more like an engine idle issue than a oil pressure issue. If the engine idle drops too low, the oil pump cannot provide sufficient oil pressure. If there is no oil light when the engine is idling normally, then there is no problem there.
