A tune-up for the 30,000 mile interval would include the following parts: New spark plugs New distributer cap and rotor New ignition wires New fuel filter New air filter New oxygen sensor Any other parts that are found to be worn out like vacuum hoses, vee belts, etc Some of the work that would need to be done includes replacing of all of the above parts and: Adjust valves Check ignition timming Compression test of all cylinders Check fuel mixture adjustment Clean and test the fuel injectors Verify that all engine systems are functioning properly Load test battery Usually do a grease job, oil change, and a complete visual inspection of the entire car noting any missing, broken, or worn parts. If the brake, clutch and coolant fluids are old, flushing and replace with new. The best thing you can do is to reference the Workshop Manual as it can give you all the details you need. Some people may just "throw" in a set of new spark plugs and call it a complete tune-up. From this short description you can see it really is a lot more than that. Most shops take their cue from the owner as to how much he wants to spend.
