You will need to remove the fuel rail, pull the injector out and put new one in. Only thing you need to remember is that you have to pay attention to "o" ring seal, making sure you remove the old one and not damage the new one. There are specific instructions for removal in any inexpensive manual.

2. Remove the throttle cable and cruis control cable, remove the throttle cable bracket, 2-10mm bolts, 1-10mm nut.
3. Remove the 2 clamps and loosen the 2 coolant hoses going to the throttle body.
4. Take off the pcv valve and vaccum line, remove the pcv hose from the rear vale cover. Disconnect the vacuum line for the fuel pressure regulator, and the vacuum line on the left rear of the upper plenum.
5. Note the placement of the spark plug wires and remove all 6 of them, unplug the coil pack, 2 connectors on each side, then remove the coil pack 2-13-mm nuts on the bottom, 2-10mm bolts on the top.
