I recently bought a 93, 40 Anniversary, 6sp, with 96K miles. It has been sitting for the last 3 years. It is basically unmolested, looks like it was maintained by the book. I decided to give it a basic tune up and change all fluids, before I start putting serious miles on it. I have changed the spark plugs but the driver side plug wires look like a nightmare. I am thinking about changing the passenger side wires and leaving the driver side wires alone for now. Any advice? Thanks, Jim
Easy. Take off the rubber that goes around the fenderwell, right above the Control Arm. Then take that plastic cover off that is held on by 5 or 6 10mm bolts. Take belt off( not all the way, just so you can take the tensioner off), take tensioner off, Then you reach under the AC unit and do one wire at a time. Simple. What do you think?

That way works, on my 92 I pulled the AIR hoses, serpentine belt, then used a 13 yo boy with small hands to disconnect the wires at the opti, thread them backwards through the bracket under the power steering pump. WARNING - MAKE SURE YOU MARK EACH WIRE SO YOU GET THEM ON THE OPTI CORRECTLY!
I have a 93 and did a complete plug and wire changeout. Check out the thread from SJW he does a very good job explaining the process for both sides of the engine. To summerize the job though, jack up the front end on both sides so everything is waist level. remove the front wheels and then the panels behind the wheels. You may also want to unbolt the ASR for added access. Your going to need to remove the serp belt and then the belt puley to get just enough room to access the Opti. I fortunately don't have very large hands so I was able to barely get the new plug wires on the opti but it was a struggle and I had cuts to prove it. Once you have the drivers side panel off the plugs are not impossible to get at. I suggest borrowing or getting an assortment of plug wrenches if you can. A universal joint as well as a socket with just a stub to finger tighten the new plugs is your friend on this one too. Your absolutely right, the passenger side is not that bad at all.... until you get to the last one (number 8). It is a queen royal beeotch to get to with a wrench. Also when putting the new plugs in don't forget the anti seize grease on the threads. Your gonna want to get new looms for the plug wires. Some if not all of the existing ones will crack and break on you. Make sure that the wires are not touching anything moving or hot. Go slow, do one wire and plug at a time, and have plenty of beer and band aids on hand. Also be prepared to curse out the GM engineers constantly.
If you want to make it really easy to see and get to the opti on the drivers side, spend $24 on the power steering pully puller/installer. It takes 3 minutes to pop off the p/s pully and you can now get your hands on the right side wires.
