Could be a few things. First I would check the oil to ensure the engine is not being starved by oil. That can be done by popping the hood, pulling out the dipstick, wiping it, then putting it back in and pulling it out to get a reading. If it is low on oil that is what will cause the light. However, if the oil level is fine it could be another cause such as bad piston rings, in which you would want someone to check your compression to ensure it is in spec.

Good luck

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.

try the crank speed/position sensor as this controls the engine revs as well as other things

Idles roughly, then low when stopped or in park, then dies. Decreasing gas mileage. Slow to accelerate


Sometimes that's caused by a vacuum leak near the manifold area.

Sometimes air in the coolant will cause an idle problem. Air will keep the air temp sensor from sending proper info.
Hope this helps.

Stopped at light. Oil light came on engine died. Restarted no power real rough. Won't idle. Is there a safety shutoff on loss of oil press. Any suggestions. 1997 3.1 lumina


Hi. This issue has several causes, but the oil light indicator is a strong sign of low pressure in the engine. This will cause the engine lubrication rate to drop, thus, producing a illuminated oil light, and erratic Oil pressure readings. The necessary actions are to have a manual oil pressure test ran on this engine, asap. When running a manual oil pressure test, you will discover if the true oil pressure is low, or normal. If the test proves that the oil pressure is, indeed, low, this will confirm that the Oil pump is suspect.

Now, if the true readings given during the manual oil pressure test are indicating that the pressure is normal, this will be the result of a failed sending unit(oil pressure switch). Although the oil pressure is suspect, this is not your only issue here. There seems to be a abnormal compression rate, present. This is causing the rough idle, and erratic RPMs. I recommend to administer a engine block compression test, as well. This test will discover if , indeed, there are issues within the cylinder heads, and block structure, such as a worn head gasket, cylinder wall issues, and cracked block. Normally, these issue will send signs, like white, or gray smoke out the tail pipe, or discolored oil. It will, also, promote erratic RPM ratings, and a rough idle. Have the oil pressure test, and engine block compression test ran, asap.

Once the test are administered, you will be able to isolate the actual problem areas, more accurately. Check the spark plug wire sets, and ignition assembly for faults, also...

Oil pressure gauge goes to 0 when idled, but goes


You could try thicker oil or stop using synthetic or add some lucas oil treatment or change the oil. The sender could be bad too. A diag is in order because if there is no presure the engine will soon die.

Oil presure sending unit

Check, if the oil level is low, top off.
If the oil level was ok then you can replace the oil sending unit.

Oil Pump light flickering + rough idle on 1996 Nissan Maxima


Sounds more like the Throttle Position Sensor or another sensor is letting the engine RPM's drop too low. When the RPM's are too low, the oil pump is not pumping enough oil.
