NOT LACK OF OIL AT ALL! FACTORY OIL PUMP OF AFTERMARKET HIGH VOLUME OIL PUMP? HOPEFULLY YOU INSTALLED DEFI GAUDE SENSOR IN PLACE OF OLD OIL PRESSURE SENSOR! ALSO OIL WEIGHT CAN AFFECT THIS ISSUE! AND LASTLY PRESSURE RELIEF VALVE MAY BE MALFUNCTIONING IN THE PUMP ITSELF

SOURCE: Oil pressure light on at idle

Don't delay on this. Take the vehicle in and have the oil pressure sensor checked. It could be just the sensor or it could be something more serious. A drop in oil pressure could lead to catastrophic engine failure.

Sounds like you have a vacuum leak in the air intake side. Check all your small and large hoses around the throttle body. Also check your idle air valve....cylindrical device connected to the the air box at the front of the engine.

SOURCE: S10 has very high idle when cold and sticks to the gas when warm

you need to replace the throtle body controll sensor. Also you may want to make sure all your linkage from the pedal to the throtle body is cleaned and lubed correctly. While playing in this direct area. Your throtle body is only 4 bolts away. Why not get some carb cleaner and get to know your truck just a litle more.

If this is a carborator, then you need to turn my warmup idle down. there are 2 sets of idles on carborators. the one to warm up the engine, automatic choke or pin settings. Get a Chilton, find out which idles pin is for what. and play a litle bit.

I think you have a throtle body so I would also check the automatic air intake sensor. It could be going bad. Check your filter and make sure its clean.

hope all this helps.

Could be the fast idle sensor check to see that the vacume line is hooked up properly.

Pull the oil dipstick and see what your oil level is at. If there is no oil on the stick then your oil level is low. Add a quart of oil and check it again. (give the oil at least 30 seconds after you finish pouring it to get down to the oil pan to register on the dipstick first). Then only add more if it still does not register on the stick. If the oil level is fine, then you may have a bad oil pressure sensor.

96 chevy cheynne 5.7 vortechas about 40to50 pounds oil pressure when first sart in morning and when it gets to temp. it drops to 20to25pnds and at a stop it goes to 0 and gauge light comes on until i give...

Well it could be the sending unit for the gauge.
But odds are the oil pump or engine bearings are worn out.
As the engine warms up, the metal spaces expand and the oil gets thinner. The oil pressure drops some under normal conditions, but not more than 10 or 15psi. Normal idle pressure with the engine warmed up is probably 25psi.
You could check oil pressure with a mechanical gauge to make sure its not the sending unit.
Once the oil pressure starts staying below 20psi for long periods you'll start hearing noises.

2001 camaro 3800 eng. when eng is cold oil pressure is high after warms up oil pressure drop very low at idle. why??

When the engine and oil are cold it will show a high pressure because of the viscosity of the oil. When it warms up the oil is thinner. If it doesn't drop below 20-25 psi at warm idle I wouldn't worry about it as that is normal.

Low oil pressure after engine warms up in 94 blazer with 4.3

I have a 99 blazer and ever since I have owned it, it reads lower in pressure when idling, but will go up too 40 while driving. This is normal for the vehicle. If the pressure gets real low, and stays low, it means its time for an oil change.

As long as the pressure goes up when you give it gas, it is fine.

When car is cold oil pressuer is at 75 lbs when car is warmed uped it drops to 40 lbs (v6 3800) when warmed uped and give it gas it goes up to 60 lbs but when i stop it dropes to 45 lbs why is this please...

When the oil is cold it is thinner or watery and the pump moves more oil as it turns making the pressure go up. As the oil warms up it thickens and the pump moves less oil letting the pressure go down. Increasing the engine speed makes the pump turn faster, therefore it moves more oil and the pressure goes up. Changing oil grades will change the numbers somewhat, for example 10W40 will give you different readings than 5W30. I don't see any problem with the readings you put in your posting. I wouldn't be concerned until the warm idle pressure gets down to about 30 or a little lower. Hope this helps.

Oil pressure high when engine cold. but fine when engine is warm

It is normal for oil pressure to be higher when the oil is cold. As the oil heats up, it will thin out. Since your oil pump is driven faster with the acceleration of the engine, your pressure will also increase. On a engine up to full temp, your oil pressure will probably be around 20 psi and maybe up to 60 at full load. But on a cold engine, you may see 60 psi at idle. I dont know if your high oil pressure is causing your vehicle to stall, but maybe your running the wrong weight/type of oil for your truck. If you live in a extreme cold area, you may want to look into a block heater to help warm up your engine faster.

High fast idle at start up.

On most newer cars there is a fast idle motor controlled by the computer that will hold the fast idle till the engine reaches a preset temp in the computer then the engine should drop down to the set idle according to specs for that car. If the oil pressure continues to stay low after the idle goes down you may need to replace the oil pressure sending unit or if worse case the oil pump.
