Disconnect the fuel lines to the fuel rail. Disconnect the electrical connections. Clear any crap out from around the bottom of the injector. Squirt a little WD40 in the injector well. Start rocking the injectors around and gently pull towards you. ---- Have new O rings to reinstall. Lubricate the O rings with engine oil.

fairly straight forward. remove nonsense, i.e. air intake, etc. thats in the way, lay out basic tools, check in advance for sizes, fuel line wrench, etc, although standard can be used if careful, or adjustable wrench if fits,...use rag and screwdriver to bleed off the fuel pressure, located on the fuel rail somewhere, remove the fuel rail that on top of the injectors, might have to unhook fuel line(s) if not flexable, replace all top o-ring gaskets on the injectors, since they might leak now if not replaced, and being very cheap, use rental tool, recommended, or if your not worried about scratches, carefully use vice grips, to pop it out, oh, and unplug the connector on the top of the injector, and dont break the cheap gd plastis thing
