1992 Lexus Sedan 400, 160,000 miles, not driven for 3 years!

What should I do to get it de-mothballed before driving? Most fluids changed out at non-dealership. Old gas still in it. Car in great shape, new battery, drove it 40 miles and now fights starting.

At the top of this page, I clicked on Search, in Keywords, I put, “car not driven in a long time”. A lot of past Car Talk responses, some related to this question, came up. I picked one about a long idle Cadillac. Here it is: http://community.cartalk.com/posts/list/589609.page
