SOURCE: 2001 daewoo lanos check engine light

oil is non conductive so I doubt that's the problem, but the oil leak should be fixed to reduce problems down the road.
as for the misfire could be a couple things, fouled plug(s), a plug wire(s) that has cracks, or even valves that are not seating which i doubt from your explanation.
I would change your plugs and wires first, and fix oil leak. if this does not fix the issue there are other things going on.

SOURCE: gauges say no pressure in engine 1995 vw golf

Get someone to check oil pressure with a mechanical gauge, to verify whether you have oil pressure or not. These engine/vehicles, have 2 warning sensors & a control module in the instrument panel. Once you know you have pressure for sure, then you can proceed from there.

SOURCE: 1997 Bonneville - Engine light code P0303

the code you have is for a misfire on #3 cylinder. (im sure you knew this right?). the crankshaft position sensor will not cause one individual cylinder to misfire. what i typicaly do in this scenario is switch the ignition wire off of the guilty cylinder onto a known good firing cylinder and see if misfire moves to the other cylinder. i repeat this process by switching the spark plug and finaly the fuel injector. a compression check may be in order as well (but not a likely cause) unless you have access to a tech 2 (gms diag computer) you will need to clear this code after each component is moved and see if you get a new code ie :p0304 if switched to #4 cylinder..other wise if you do have access to a computer that has a misfire chart in its features you can quickly identify the guilty component. as i side note the ignition coil may also be faulty, but i believe your vehicle has a 3.8liter meaning that it has a coil pack....switch the others i listed and see ow you make out....good luck!

SOURCE: Engine has knocking noise. Oil is good. Started

Engine knock Huh? In order to qualify the term "Knock", Let me get you to perform some simple task/observation. Typically, if you hear a noise on top of your motor that can be described as a light knock, usually going tap, tap, tap, tapping along at double the tempo, of your motor spinning, Your oil pump may be having trouble getting oil to the top where the valve's and rocker arms are. If you hear a "Knock" by bending over or kneeling beside one of your "front wheel well's"and stick your head up to the well, providing a vantage point to "hear" whats going on at the lower part of the engine. A knock from here will/can indicate a potentially overheated, under lubricated, rod or crank bearing that could seize the motor. This (theretical) crank bearing would be sounding off at half the tempo of the rocker arms above., with a deep, dark klunk that would defintly present itself as the sort of noise that damages metal parts. Now, that being said.....common sense goes a long way, people....1.) Most people are aware of the maintenance that has been performed on a particular engine, the quality and quantity of that maint. and when the last time it was ran out of oil or water. For those who fall into the " lack of maintenence" catagory, you probably already know why your engine or driveline sound as it does. If you happen to take particulary good care of your car, there is a good chance that whatever noise or "happening" might be going on, it'll be much easier to remedy. There are always exceptions to every rule. Remember, its not what will happen, it's what can happen. Take care of your car, and it will take care of you. Theroad

Engine is running fine. Oil level is good. Oil light comes on and off at random. Engine isn't knocking and runs great. Recently changed to GTX extended milage oil. Problem developed


The oil light comes on when the oil pressure sensor detects low oil pressure. The amount of oil has little to with it, although very low oil levels can cause loss of oil pressure. Since you aren't getting knocking, chances are the oil pressure sensor is defective. Replace it and monitor the situation closely. This could be a serious condition if allowed to escalated and it turns out to be an oil pressure issue.

Replaced oil sensor light still comes on


MAY---May-be you really have low oil pressure.. The way this sensor works is when you turn off the engine it closes to ground.. and when you start the engine.. the oil pressure opens it and the light goes out.. SO.. if the wire going to it is grounded out somewhere between the sensor and the dash board the light will stay on.. 3 choices.. 1. bad sensor (even though you replaced it) 2. wire is shorted to ground.. remove wire from sensor while engine is running.. light should go out. 3. you actually have really low oil presure. next.. after you have exuasted #1-2. you can remove sensor and install a real oil pressure guage and see what the pressure really is.. If you have very low or no oil pressure..1. Check oil level.(probably should have done this first) 2.pull oil pan and replace oil pump.. while you are there check a main bearing and a rod bearing for wear.. worn out bearings will cause low oil pressure. If you have good oil pressure install the pressure guage permanetly and forget about light.

Most likely The fuel pump is going bad. Also the engine oil running below 1 quart can cause engine shut down(Engine Oil Light). The fuel pump and low oil shut down will not register a fault code. The cheapest approach to your problem is to, Make oil level correct, change air filter, change fuel filter And add 1 can of B&G44K to a full tank of 91 octane fuel. This additive is the best on the market and only available through dealerships(Do not use substitutes).The B&G will condition the fuel pump and injectors and increase MPG. and improve drivability.

1999 malibu 3.1 clyd 5 missfire and now random missfire oil light is on lfters very noise runs rough


Have you confirmed there is no oil pressure and the oil level is full on the dipstick?

The oil pump is turned by the oil pump drive located under the throttle body. The oil pump drive is run of from the cam shaft. It is not uncommon for the camshafts to break on these engines.

It may not be a bad idea to pull the front valve cover and turn the engine over by hand to see if all the rockers are moving.

What does "random misfire" diagnosis mean on 06 Suzuki Forenza?


From what you are sharing, it sounds like you may have worn piston rings. This could be why you had oil on the spark plugs. It might of been a problem which may have also reached your catalytic converter, where your O2 sensor is located. As for the noise you hear, are you able to determine where the noise is coming from ? Are there any bubbles inside the coolant reservoir ? If yes, you may have a cracked cylinder hear, blown head gasket or cracked block. You may need more specific troubleshooting to determine this.
If the noise is coming from the air filter box area, you may have bad intake valves. There are many possible issues which could cause your problem. Further diagnosis is required.
Random misfires mean that when your car is started, not all cylinders are firing at the proper time, this may be due to a bad / worn timing belt / chain. A bad cam or crankshaft sensor. There could be a few other individual problems.
Do you have any other codes other then O2 sensor in the engine control module ?

Noise from engine


Does the noise come from the engine or transmission, Pull the dipstick tube from the transmission when it is warm and smell it for a burnt smell.Check oil dipstick for any water or white paste.
