SOURCE: 2002 Mitsubishi Lancer Oil Light at Low RPMS.

I had the same exact problem over the weekend. We decided to go cheap first and replace the Oil Pressure Switch. It's like $6.00 at Auto Zone here in Texas. (don't know if you are from the states). It ended up being the switch. It's located right by the oil filter and it's very easy to change. Just make sure you have a wrench or deep socket bigger than 15/16. I think we used a 1 inch wrench.

If it's not the switch, its most likely the oil pump, but don't forget to check the hose, it could be bent or crimped.

Hope this helps :D

SOURCE: 93 mitsubishi diamante, starts runs for 5 mins

Check all of the cables near intake. Make sure all of the sensors are pluged in.  Since if sensors have plugs that are loose than you could have a problem of inconsistent runing.

It's definitely your injection pump seals mate.....common prob with these engines. My 1994 2.8TD was exactly the same until I had the sealls replaced. I went for the complete reconditioning and not just the main seal and it cost me £519 in total. Dunks

2006 Chrysler 300 Touring AWD misfire when put in reverse - Cold Start

A blinken lite means the cat converter is bad. Unplug the computer n clean the pins then replug. Connections on old cars often get dirty. Get a datastream run at a privateshop to target issue.Its better then a code reader. Wiring harness should be inspected for flaws

2000 chevrolet silverado 4.3 litre engine multiple misfires especially when cold

How long since a tune-up? Any applicable trouble codes? If you have the spider fuel system, that system is noted for problems. I have seen service bulletins with this system, problem with cold start up. After the first start-up, the vehicle may run fine the rest of the day. The problem was fuel poppets sticking. The fix was to clean the fuel poppets, the cleaning procedure I saw was a shop procedure.

Generally, with misfire, check spark--fuel--compression.

Polo 1.4 petrol 2007 poor ideling at cold starting

Sounds like you have a misfire before the car is heated up properly. Because it runs well after warmed up, I'm thinking that your fuel system, and compression are good. The only other thing that could cause a misfire is an ignition problem. Most likely you have a spark plug that is fouled and does not work well or at all when the engine is cold, but when it warms up to the proper temp it self-cleans and begins to function again.

Another possibility is bad fuel that does not atomize easily when the engine is cold. I would change whatever hasn't been changed in awhile. Spark plugs or fuel.

I have a magna 1997 when it is hot and i turn it off it will not start again a

That is a TE magna 3rd gen either a 3 .3,5 ltr motor .. . I take it it will crank over ok so either fuel or spark
Is this an Auto , triptronic or manual box ?..is it running on gas ? .These no starting problems require a scanner to sort out if intermittent or unresolved ... . for now try these basic things .
For Fuel .check if the fuel filter has been changed and the fuel pump is working when hot There is a pressure regulator on the fuel rail . injectors cleaned ? For Spark -dissy. coil ..exciter. leads .plugs any of these can fail when hot .. I am in several Magna forums so should be able to sort this

1995 dodge neon cuts out during normal driving runs at full throttle

hi I assume this is a fuel injection vehicle and if so it sounds a lot like you have a throttle body problem or throttle sensor problem ,have you also checked that the fuel filter is not blocked,remove the fuel filter and blow thru it in the direction of flow and if your cheeks blow up while blowing thru the filter it is blocked or restricted -replace.
hope that helps .

Has a 6.0 L with bad misfire under a load and is

Hi Brad,
I ran into the same problem your going thru,
swapped cylinder plug and wire ,and the scan kep telling me it was still seeing the problem on the same cylinder,
smoked it too,nothing made sense!
Until i took the whole fuel rail off carefully not to let the fuel run out all over the engine,Had a white rag folded up and handy,tilted the rail assembly and left the fuel run on the cloth,OMG! the rust that came out of there,
I pulled every injector out of the rail,cleaned the inside of the rail with air pressure and carb cleaner.
Its when I was checking the injectors that I found the culprit,the rust pieces had made it thru the injector but were trapped in the screen of the injector!
I hope this cures your.
