Question about Cars & Trucks
The intemitent gage star went are over 1500 revolution
Replace the oil sensor. I've also seen this happen when someone puts in custom stereo equipment and draws power off the oil gauge in the dash. See if it happens with the stereo off.

I hate be the bearer of bad news but it sounds like you bottom end bearings are getting worn out. You have excessive bearing clearances causing your drop in oil pressure.

these cars have problems with bad oil pressure warning switches you may have someone put an oil pressure gauge on the car and make sure your pressure is within spec and go ahead and change the sender if it checks out please rate -jeff

I had the same issue. On the back of the engine (behind steering column) you'll see a pressure sensor with a wire going to it...check your connection. If that doesn't work, then your pressure sensor is probably at the end of it's road. You can get a new one for about 15 bucks at any parts store...hope this helps

SOURCE: Low Oil Pressure and rough idle
Please understand, all I can offer you are suggestions, since I don't have access to hands on testing. You might first change oil and filter.
If going by the oil pressure guage, low oil pressure can mean worn crankshaft bearings, as the clearance between bearings and crankshaft is what determines oil pressure.
Of course a worn oil pump can cause the same problem.
You might want to connect an external oil pressure guage to the engine to verify the pressure reading.
The rough running at this point would be hard to pin poit.
Because I do not know the extent of the rust, I can suggest that you consider having it undercoated.
Again, I can only make suggestion because you need an absoluate diagnosis.

HI. this could be a faulty sensor or a bad oil pump screen as well. the oil pump malfunction is the worst scenario in this case. You can actually test the sensor with a voltage needle to see if its getting the proper voltage. i would inspect the wires that are attached to the sensor as well. if the wires are good and the current level is ok as well, it will most likely be a faulty oil pump or bad oil pump screen as well.
In this case, i would recommend inspecting the oil pump assembly. here is a inspection guide below that will help you confirm oil pump failure.
--OIL PUMP INSPECTION GUIDE--
The internal parts of the oil pump are not serviced separately. If wear or damage is noted, replace the entire pump assembly.
Please rate and have a great day:)
