SOURCE: flashig oil light
You either have a loose/worn engine bearing or a worn out oil pump, do not drive the car this way, you will cause serious damage to the whole engine. A oil switch is for a light, it turns on the light when oil pressure falls below about 10 PSI, a sending unit is for a guage that shows oil pressure with a scale, it may have numbers on the guage or just green and red, or high and low.

SOURCE: high idle/low idle pattern
This issue is caused by the egr valve being stuck open, more than likely. Just remove it and clean the plunger on it. Also clean out the two ports that are in the intake. Check out saturnfans.com for more information. I hope this helps.

did you change the screen with the oil pump?
sometimes the screen will get clogged up and lose oil pressure.

SOURCE: 4wd high 4wd low lights flashing
When the 4WD lights flash on and off,
this indicates that there are 4WD-related trouble codes in the 4WD
control module. Sometimes 4WD lights never illuminate.
The first step in diagnosing the system is to establish communication and retrieve trouble codes from the control module. After retrieving the codes, write them down, clear the codes and retest to see which codes are regenerated. False codes can be set if a component is disconnected when the key is turned on.
If the 4WD lights flash on and off, and no codes are found in the 4WD control module, try clearing the codes anyway. After a certain amount of key cycles, the codes will normally clear from the 4WD control module, but the module will not respond to commands until it is re-initialized by clearing the codes or disconnecting the battery to erase its memory.
If your scan tool will not communicate with the 4WD module, first verify that the scan tool has the proper software and the latest updates. If it does, then try another scan tool. If it still has no communication, the power and grounds that are supplied to the module will need to be tested. See if the scan tool will communicate with the other modules on the shared communication network. If they're OK, check the harness from the data link connector (DLC) for an open circuit to the 4WD module.
