My gas milage has decrease in last few months. Even before it got colder. How often do I have to replace fuel injectors. I replace the fuel filter, plugs, cleaned the intake, and had the rest of tune up done at nissan about 6 months ago.

That doesn't sound like injectors, more likely an O2 sensor issue etc.
