Seeing as I too am in Elizabeth you would figure I'd have a good answer for you. Unfortunately, I do not. Most of the shops I have taken my car to have ZERO clue how to work on the LS and assume it's similar to a Town Car, since Elizabeth is near the airport. Therefore, all of the mechanical work done to my LS I have done myself. The only things I've done at shops are: exhaust and tire related things. Most of the things you need to do you can do yourself using the tech articles above. What exactly do you need to do? When you say tune up are you referring to: fuel filter, plugs, cops, air filter? All of those things can be done VERY easily with minimal tools. If you need help let me know. You can PM me, or you can even stop by where I live and I can help you. Do be aware - as I'm sure you are I live in Elizabeth and don't own a garage, I do have a driveway though!
