Hi,
Does the engine have to be rotated to change the back plugs on the 3.4L engine? If not how are they accessed?
Thanks

Welcome to AF !
u sure its not a 3.1 in ur 94 ?
Anyway, you just hav to grin and yell to get back there.
A short extention and maybe a swivle sparkplug socket.
You should not hav to rotate anything. The coil packs are probly in the way, but this job is done pretty much blind, totally be feel :thumbsup:
Good Luck

Thanks, I was afraid of that.
Definitely a 3.4. I can't even remove the wires, they are blocked by a support that extends between the struts. Its only about an inch or so wide, but just enough to block access. Could this be a support only on the convertible? I have the shop manual for a 92 Lumina, but the 3.4 diagrams do not show this support.

OK, you might hav to remove that and if I remember right the upper intake might even hav to be removed for ease of acess.
A spark plug boot tool works best, since they probly hav that metal heat shield on them.
And be carfull If you use a swivle type sockets,
sometime shear force can break the plug off
in the head :eek7: and thats no good !
