If you want to work on your car its almost a guaranty that you will have to buy a repair manual for your car, which for the only ones worth it, its kind of pricey, another option which i learned about today, was that alldata (owned by autozone) has a diy internet service where for the first car i believe it is 26.95 or something for one year and the second car is like 16.95 for one year, its basically the book on your car, that autozone bought and is now selling it to you for way cheaper its deffinitly worth it
