What makes fuel injectors go bad?

Can I replace just one injector Duramax?
When it comes to your diesel fuel injection system, a single injector is often the cause of an entire engine failure. When you have become the expert on your 2005 Duramax diesel system or other industry equivalent, it might be tempting to just replace that one nozzle and be done with it.
How important is the fuel injector?
Fuel injectors are nozzles that deliver a measured high-pressure spray of fuel into your engine's combustion chambers. Your computerized engine tells the fuel injector when and how much fuel should be delivered thousands of times per minute in all diesel and gas-powered vehicles.
Can you mix old gas with new?
Old and new gas should not be mixed for a variety of reasons, the major ones are; The old gas degrades over time it should not be added because it has already lost it's combustibility. It can cause sputtering. It might fail to fire it up.
How long is gas good for in a can?
In general, pure gas begins to degrade and lose its combustibility as a result of oxidation and evaporation in three to six months, if stored in a sealed and labeled metal or plastic container. Ethanol-gasoline blends have a shorter shelf life of two to three months.

What is the code for a bad fuel injector?
The most common fault codes associated with a clogged fuel injector are P0171 and P0174, which indicates the engine controller is seeing a lean condition. It is also possible to see fault codes for a rich condition if the injector is leaking or not atomizing correctly.
