Disconnect battery, harness for the iacv, egr position sensor, and maf sensor if you have one. Remove airbox from throttle body, removed throttle body cable from throttle body and the bracket as well via 2 bolts. Carefully remove the vacuum lines from the egr valve, throttle body and the breather lines from the throttle body by loosening the small clamps. Then unbolt the 6 throttle body bolts, two in the rear two under the "5.0" plate and two in the front. Carefully lift the throttle body up and out of the way looking to free any vacuum or electrical lines. After that depressurize the fuel system. There's a little valve that sticks out kf the fuel rail by the alternator. It kind of looks like an a/c port. After the pressure is released just remove the two bolts that hold down the fuel rail, pull the electrical connectors gently from each injector and gently pull and work the fuel rail until the injectors come out from the lower intake plenum. Just gently pull the injectors out of the fuel rails. Make sure the new injectors have new o rings if they don't already and lube the o rings with either fuel or a silicone based grease. I honestly use "permatex dielectric grease" it's clear and easy. I wouldn't recommend using vasoline because it doesn't really dry. Install the injectors in the fuel rail first and then all together into the plenum(easier this way). Same thing for the other side. To put it all back its just the opposite of the removal.
