injectors

i have a bad injector in my 2000 3.4 v6. has anyone replaced one before? it seems like it shouldn't be too hard, but i am looking for any tips you have

The key step to replacing a fuel injector on the 3.4L is removing the upper intake manifold and the throttle body. Disconnect all vacuum lines and electrical connectors. Be sure to mark them and remember where they go. Then you'll need to remove the respective fuel injector rail with the suspected bad injector. Be sure to put new upper and lower injector seals in and new UIM gaskets. Properly torque all bolts to specs.
