How's it going. Just joined the forum as I just purchased back a 02 GS300 from my sister that I had sold to her 2 years ago. The car has 104,400 miles and is in excellent condition and maintained. But, I would like to do a tune up, so I called dealer and they want $300 just to change 6 spark plugs and this is all they do apparently. I thought a tune up was more involved like making adjustments, changing oil/filter, you know other stuff but I guess I am wrong. So i am thinking I will try this myself. Other than chaning the spark plugs and oil/filter, what else should I consider doing for a tune up?
Many thanks.
