Proud owner of 98 base. Needs some TLC. Just did a brake booster and that was a lot of fun but brakes are pretty high on my standards. After studying a lil my car has a sct badge on the back. How do I know if some has put in a tune and if it is still working? Owner was an older woman who said she bought from an old man original owner. Has the intake box swapped to kn cold air and the 3rd cat and resignater removed. Passed inspection so it will be here for a while. Cars name is Kiki my fiancee loving name. She had it in here head that it was a mercury marquis she isn't a car girl but lets me do pretty much anything I need to so.... Anyway hope to learn from other mistakes and help were I can!
