Sounds like an ignition component failure check for proper resistance through primary and secondary ignition coil windings, refer to service repair manual for exact specs, also the ignitor magnetic pick up may be not up to snuff, the only other ignition component to replace or check is the ignition module and/or plug wires themselves, sometimes when extreme demand is put on the ignition system the plug wires must be high quality and completely isolated from one another. Spark plug wires when routing cannot come in contact with one another in the slightest proximity.

Did you prime the new pump properly before installing?

SOURCE: 94 f350 7.3l turbo diesel looses oil pressure as rpm increase

Before you spend money on a new gauge. Get an oil pressure testing gauge for $20 , remove the oil pressure sending unit and test the oil pressure. If oil pressure at idle and 3000 rpm's is a-ok via spec's ( big money repair items) then its either the gauge a clogged or defective sending unit or the circuitry. (little money repair items)
You can also have this done at a repair shop.

SOURCE: oil light comes on after

If you did the sump drop; you should also do the PCV #6 upgrade. I would'nt look at the oil pump yet. You may have a bad oil sensor. Did you remove the valve cover to see what it looks like? you could have a clooged breather port. Did you do an engine flush before you dropped the sump? If you remove the VC start the engine to see if oil squirts out then you will know if the pump is good.

How can I cheat the Idle up? I'm getting a low oil pressure light at Idle, 800 RPM. I would like to increase the Idle to 1000 to keep from getting the light.


that wont work trying to adjust idle can be done on older cars with a carburetor or the older throttle bodies new vehicles trying to do it will set off check engine lights on most sensors sound more like oil worn out---oil filter or pump problem change oil and filter and do a flush ---and put in an additive such as lukas - royal purple etc---also why did head need replacing was oil pump tested

My oil light comes on after higher speeds while idling at a traffic light.


It may be your oil pressure transmitter switch at fault. There's many different oil pressure transmitter switches. Here are some generic images:
oil pressure transmitter switch Google Search
It could also be that your vehicle is due an oil/filter change.
Is your oil level ok?

It's unlikely to be your oil pump at fault.
  1. Check your oil level
  2. Is the vehicle due an oil/filter change?
The oil pressure transmitter switch simply tells the engine 'low oil pressure'. This usually happens at idling speed due to a faulty transmitter switch, low oil level or there's a need for an oil change as the old oil is no longer up to the job. Oil pressure switches are easily changed.

The important thing is that you aren't getting a warning light when driving at speed. If your oil level is okay and it isn't due an oil/filter change - it probably is the oil pressure switch at fault.

For your own peace of mind try adding an oil additive.

Oil light on after engine warm-up on idle


this means a mechanical gauge test is required to check actual pressure warm idling if low below 20 psi then the oil pressure pump relief is stuck open or engine bearing are worn

Oil pressure light staying on when ticking over,or braking


The fault is indicating low oil pressure, when the engine revs are low the oil pressure drops, first thing to do is change the oil pressure switch (cheapest option), see if that cures the fault. If not have the oil pressure checked, if the fault is the oil pump, then it could cause serious engine damage. Needs to be check out as soon as possible. Good Luck

Everytime we stop at light the oil light comes on then turns off as soon as gas pedal is pressed


The oil lights come on because there isn't enough oil pressure in the engine... When you come to a red light, the engine is at idle in a lower rpm and there isn't enought oil in your engine to cycle, thus creating low pressure, and the indicator comes on, however when you rev your engine or press the gas pedal, the remaining oil that you have in your engine is being cylce because of higher rpm, thus bypassing the oil sensor. Solution to this, is you need to add oil to the apropriate oil level AS SOON AS POSSIBLE or get a oil change before driving this car any longer as major mechanical issue may occur if you do not get this taken care of. You can buy a quart of oil at walmart or your local gas station and add it and get you by until you get it to the gas station. You may want to constantly keep a eye on the oil level as maybe your engine is burning oil, in order to avoid engine break down.

My car is Volkswagen polo 2001 1.4 automat. After driving 8-10 miles at a low speed(30-40 mile/h) oil pressure warning appear at the dash board. When I push the accelerator the oil pressure warning...


Do not assume that the low oil pressure warning is a false one or that you only have a faulty oil pressure sensor. Your engine may in fact be running with low oil pressure once the oil heats up and thins out. 8-10 miles of running is enough to get the oil hot. It is significant that you only get the low oil pressure warning once the engine oil is warmed up.

If the oil pressure in the engine is low, engine lubrication will be impaired and the engine can be badly damaged so you need to run an engine oil pressure check.

1. How long has it been since you have changed the oil in the engine? If it has not been changed in the past 6 months then change it and change the oil filter at the same time. You must only use the oil specified by VW for that particular engine.

2. When new oil is heated it thins. If it is old and contaminated it will be even thinner when warm. You will get less oil pressure when the oil is thin and hot and more oil pressure when it is thick and cold. Fresh new oil is a little thicker as it has not been diluted with petrol and other contaminants.
Oil pressure also varies with engine speed (RPM). At idle or low engine RPM the oil pressure is lower.

3. OIL PRESSURE CHECK
After the oil is changed the car needs to be run to check if the oil pressure warning still appears. (I suspect that it probably will). If it does appear then an independent oil pressure gauge needs to be connected up to the lubrication system in the car to check the engine oil pressure. This is best done when the engine oil is hot because this is when you are getting the low pressure warning. Any competent mechanic will be able to do this. ( The useless ones will not). The oil pressure can then be properly checked on the gauge at various engine RPM. If there is a low oil pressure reading from the gauge then there could be a problem with the oil pump, the oil pick up or the oil pressure relief valve in the engine.

4. You mentioned that you see the oil pressure warning disappears once you accelerate. I suggest this is only occurring because with an increase in engine speed (higher RPM) the oil pump speed is increasing and the low oil pressure problem is being overcome temporarily. However as soon as the engine RPM drops the oil warning will appear again which means the engine is running with below minimum oil pressure at that RPM.

Even when you get no warning, the oil pressure in the engine could still be running significantly below the optimum level.


5. It is possible that the oil pressure is fine and that the problem is an electrical gremlin as these cars suffer from a variety of electrical faults. However from what you have described I think there is a problem with low oil pressure in the engine and until it is properly checked it is unwise to assume that you are just getting false oil pressure warnings.

I hope this helps.

Problem with it is the oil light comes on when at a stop sign or at a red light but then goes off when you get going. But it's not leaking any oil, has had oil changes regularly


It's most likely one of two things: Your engine could be low enough on oil pressure when idling that the light is coming on for that exact reason or your oil pressure sensing switch could be faulty and misreading the actual oil pressure and erroneously turning on the light. The only real way to tell is to have someone remove the oil pressure sensing switch and temporarily install a mechanical test gauge in its place to check the actual oil pressure available. If it's low then there is an internal engine problem of some sort. If the pressure is about 10 psi or higher at an idle and 30 psi plus at 2500 rpm then your sender is at fault.

Oil light comes on


Hi, this is an oil pump issue. i recommend replacing this device and the oil screen as well.

The oil pump is a device that distributes the oil throughout the engine. at high rpm's the demand on this device increases dramatically and, if it is malfunctioning in any way, this high demand can not be met and the needed lubrication will be shorted, therefore, tripping the oil light. Most damaged oil pumps can produce enough pressure during low idles but, when the rpm's are increased, the malfunctioning pump will fail to meet expectations. this will cause low pressure and inadequate oil flow. this can also damage the block in time if not corrected.

I would do a quick oil level check to make sure of proper oil level. if the oil level is proper, you will need to replace the oil pump asap. if the oil level is low(1-2qts low), just add to full mark and, run a test drive. if the light illuminates once more, this will confirm oil pump failure and it will need to be replaced.

Remember to replace the oil screen as well.

Please rate and god bless:)

Oil pressure gauge drops when de-exacelration


I had the same problem with My jeep, when i took it in to a shop, they couldn't find any problems, , after about 5 shops and a ton of headaches from the low oil pressure warning, they found out that the gauge had gone bad, you may want to look into it as well.
