Hi Bill,
Congrats on the Ruby Zee!
You may be surprised and not need to pull the plenum for awhile. As you may know, injector replacement is mainly confined to the early years (90~92). For 1993 models & up, ethanol tolerant injectors were installed. If you do encounter a miss or stumble, I suggest trouble shooting ignition issues first.
Also, should you desire to replace plug wires at some point, keep your original wires with LT5 stenciling. They are no longer available and even used ones are expensive.
