Ok my 94 z28 a4 is running really crapping (alot of jerking at slow speeds). So I think one of my plugs might be fouled out since me and a buddy started unhooking the injecter wires and it stayed running the same for one of the wires (3rd plug on passenger side) so i check the wires to the opti and they were good. I tryed to check the wire on the plug but I couldnt get my hand any where close to it. So my question is how do you get to that plug? I really do wanna use a shop to change my spark plugs.

 

I've found the best way to get at the back two plugs on that side is from the bottom. Remove the exhaust y-pipe and you can reach right up there....

Be careful..the studs on the y-pipe often break leaving you with more work.....
