Well when your computer sees that the oil pressure is too low it will shut the fuel pump down as a safety precaution. What could be causing the low oil pressure could be a few things. You could just be low on oil (5 qts is standard on most vehicles), your piston rings could be going bad causing you to lose compression, your head/valve cover gaskets could be breaking down which could cause you to lose compression, and your valves could be covered in carbon build up and not seating completely.  Try this; put a quart of oil in and try running some 44k power enhancer through your engine. If you are still getting the low pressure light it could be a mechanical problem such as your rings, gaskets, Etc.
The high idle could be a number of things. Your Throttle cable could be adjusted a little short, your Engine Coolant Temp sensor could be constantly reading that your engine is cold which would then dump more fuel into your cylinders. Your O2 sensor could be going out therefore constantly reading that there is too much oxygen in your exhaust and telling your computer to dump more fuel into the engine. Its a long shot but you may also have a timing problem.... Good luck and if there is naything else I can help with just let me know...

How can I fix my car with the oil light coming on. The engine does intermittent jerking during driving


Oil light usually indicates LOW oil pressure.. Which will kill your engi ne and cause very expense repairs. FIRST Check oil level, If the level is good. You need to find out if the engine really has low oil pressure. A new oil pressure switch is about $8.00 you might start there. If the light still comes on its a good posibilty your car has bad oil pres.. To find out for sure you will need to install a Pressure guage and check the actual pressure.. If the Oil Level is good and you still have low oil pressure The engine has internal wear or damage.. You should not drive it till you fix the low pressure problem. rebuild or replace engine. The intermittant "jerking" can be unrelated to the oil pres problem or you engine is going away because of the pressure problem.

My oil light comes on when i stop and blinks when im driving why does it do that


This light has nothing to do with oil level, it's oil pressure that is low here and turniong on the light, If you do have low oil pressure in the engine you will shortly be needing a new engine, SO HAVE IT CHECKED RIGHT AWAY. It may be a faulty pressure sensor or other problem.

On a hyundai tiburon how do i know if the oil pressure is bad


If you have low oil pressure you should have a waring light or message, the engine will become noisy and if it is not repaired very soon you will here first a loud tapping noise then a loud knocking deep in the engine, and finally the engine will worst case blow up and parts may come out the bottom through the oil pan. Never drive any car that shows a low oil pressure warning light or message, stop the engine right away and have it checked by a shop.

Why does my low oil pressure light comes on when making left and right turns


A bad oil pump could cause this but i would double check the oil level when the engine is hot on a level surface. That light usually only comes on when you have a low oil level and make turns starving the oil pump.You should do an oil pressure test to make sure it is the oil pump. However seeing that it only comes on when you take hard turns, it makes me believe that is may be an exposed wire that grounds out when you make a hard turn

On my 93 Dodge Caravan ES 3.3L, when it comes to a stop and idles (at a light mostly) the check gauges light comes on. When the check gauges light comes on the oil gauge is at the bottom. When I tap...


Okay What it means is that the oil in your car is either low in level or the oil pressure at low revolutions is low. I highly recommend you to stop driving the car when this happen because you can internally damage the engine with a low oil or a low pressure of oil. Check the oil level first..make sure level is fine and oil looks good. Black and burned oil will give you a low oil pressure as well. If it happen that your car need a oil change. Make sure you get it done and see if the problem goes away. Very rarely oils pressure sensor goes bad but if oil is new and level is fine you can take the oil pressure sensor and connect a tester for a oil pressure. If this is not under the manufacturer specifications.. oil pump is worn out and you have to replace it for a new one.
Good luck and don't forget to rte me. Thanks

I have a 1999 Dodge Stratus and when the car comes to a complete stop after its been warmed up, the oil light comes on. This goes away as soon as I step on the gas. I've checked the oil and there is a...


The oil pump may be going out - the light indicates the pressure is below the proper level and when you step on the gas it spins faster/raises the pressure back up to an acceptable level.

This is something to get checked RIGHT AWAY, as these cars have a history of engine failure....possibly due to low oil pressure.

Check this LINK for more info.

The emissions system may be related, but get the oil pressure issue fixed 1st.

My low pressure oil light keeps coming on when i stop and i just got my oil changed. The oil is not low. What could be the problem?


Hi,
That means LOW PRESSURE , not low in volume. Pressure is measured in PSI. The reason that your light comes on when you are at a stop is because your engine goes to idle at a stop and would normally have lower pressure. That doesn't mean you should get a low pressure light though.. I would have it checked by a pro right away as this could be your first warning before a serious problem.
