Search for DIY on here there has been a post on before

 

Are you tuning the computer for the new injectors? If not, your idle will fluctuate.

What injectors are you using for replacements? I know that RC injectors require a thicker o-ring where the injector seats into the intake manifold.

 

Soory they are same but they new, do you know how to change them??

 

The key is to depressureize the fuel rail to prevent gasoline from spraying. You can leave the car sit for about an hour to relieve most of the pressure. Place rage beaneath the fuel rail to catch any gasoline.

You simply pull the fuel rail, remove the old injectors, insert the new ones, and reinstall the fuel rail.

 

^yup. hayes also recommends to take off the gas cap to relieve pressure.

take off the vacuum line and fuel line on the fuel pressure regulator. Than the nuts holding on the fuel rail and the injectors should be pretty easy to get to. installing it is just the opposite.

also a manual for your car will be the best buy you've ever made.
