1) the engine oil level is low
2) the engine oil is old - making it very thin, especially after the engine warms up.
Likely the oil light is doing its job and calling your attention to the level and condition of the engine oil.

It needs a new engine... :(
An oil leak.

It is possibley your alternator or battery
You might need to change the fuel filter.
There are four causes of the engine failure. The four causes of the engine failure includes engine overheating, lubrication problems, misassembly , and detonation.
Probably a misfire condition, however you will need to hook up a scanner to read the codes.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
Check the alternator output, you may have a failed voltage regulator or bad brushes in the alternator resulting in an oscillating voltage value. This assumes that the flicker is relalted to engine rpms.
If the loose cable is the main one from the negative side of the battery, then everything will flicker simultaneously with the key on and the engine stopped. When the engine is running, the alternator will keep things energized. If you have a loose groung cable on one particular accessory, only that accessory will flicker or just remain off.
My car flutters while at stop signs or lights. I've just had a head gasket put on..... the flutters are light and some times occurs. I've read the engine may be full of Carbon dioxide. Should I put a higher octane in the tank would that help like it said. Thanks!
