Hi I just bought this car and the ABS light turned on. The mechanics are charging me a lot just to check what does that means. I wanna know an opinion before going to the shop. It's a 1998 Chrysler Cirrus LXi and the mechanic wants to change the Gasket also. How much does this part usually costs? How about the spark plugs, he said that I need to do the tune up because to change the spark plugs he needs to open the top of the engine. Thanks for any advice! Eduardo
