There are many steps involved, but it is not a difficult process.

What You'll Learn
It's not hard, but there are a lot of little steps
It's not hard to replace fuel injectors, but there are a lot of little steps. It's recommended that you follow the recommendations in the service manual for depressurising the fuel system before you start work on it. If you don't have a service manual, you can depressurise the fuel lines by disconnecting or removing the fuel pump relay, and then running the engine until it burns away the fuel in the lines and stalls. It's also possible to depressurise the fuel system by depressing the Schraeder valve on the fuel rail with a cloth underneath to collect the small amount of fuel that will be released.
Once the wiring and fuel rail have been removed, the injectors just snap in and out and are held in place by their o-rings. Make sure to lube up the o-ring really well or you'll tear it trying to put it back in. It's also recommended that you purchase new injectors designed for your specific engine and dip the tips in fuel before reinstalling the injectors and fuel rail.

It's expensive
Replacing fuel injectors can be expensive. Although it is not a particularly difficult task, there are a lot of little steps involved, and it can be dangerous. It is recommended that you have a professional do the job for you.
If you are replacing the fuel injectors yourself, you will need to purchase new injectors that are designed for your specific engine. You will also need to depressurise the fuel system before you start work. This can be done by following the recommendations in the service manual, or by disconnecting or removing the fuel pump relay and then running the engine until it burns away the fuel in the lines and stalls. It is also possible to depressurise the fuel system by depressing the Schraeder valve on the fuel rail, with a cloth underneath to collect the released fuel.
Once the fuel system has been depressurised, the injectors are relatively easy to replace. They are held in place by their o-rings, which need to be well-lubricated to avoid tearing when putting them back in.
It is worth noting that fuel injectors do not often go bad, so it may be more cost-effective to simply replace the one that is faulty, rather than replacing them all. However, if one has gone bad, it is possible that some of the others may also be close to failing.
