Car still runs perfect, but now is the time before anything goes wrong. I know about the timing belt already. I really just want to buy oem parts (what is the best and cheapest online oem parts place?) and do a complete tune up, but I need advice on how deep I should go. I know the basics: plugs, wires and such, but what else? Should I replace the coils, or are they fine still? A complete list of everything I should do would be awesome from someone in the know. Thanks
