2003 mountaineer issues

[kcain]

Hello all,
I havea 2003 Mercury Mountaineer which have a fail code of p0 442 and today it started to idle high and low with a message ugh low engine pressure. Once I added Oil to the engine the idling stopped for a while and allowed me to return home. But once I tried to turn into a parking spot the truck cut off. Then the truck started right back up again but was idling high and low there's anyone have a solution.?
