How to change plugs and wires on a 84 z28?

Answer 1

you have to go at it from the bottom. I have had several irocs and this is how you do it. Take off the front wheels and reach up from the inner fender well. You can't seen the plugs but you can feel them. It takes time but it's the only way. they can be changed from the top, you need a ratchet, 5/8" spark plug socket and a collection of diffrent sized extensions, just pull the wires loose then fit the socket over the plugs and take them out, when putting back in, tighten by hand until firm then use wrench for 1/4 turn more.
