2002 mountaineer check guage light

The check guage light on my 2002 mountaineer v8 comes on sporatically, for a few seconds. It happens alot when turning. Any ideas??

I have a full tank of gas, the coolant temperature is fine, and the oil pressure is good.


After further observation the oil pressure guage does bottom out for a second or two causing the check guage light to come on
then goes back up to normal causing the light to go out. It seems to happen when accelorating and stopping quickly, also when turning.
