"Tune UP" is a little different from "Scheduled Service". If you are tuning the engine, there are some basic steps.

A basic tune-up MUST include:
* Cooling system inspection;
* Clean or replace spark plugs;
* Ignition wire testing;
* Distributor cap/rotor (if you don't have the OptiSpark);
* PCV valve cleaning or replacement;
* Air filter;
* Cleaning the IAC;
* Checking/setting TPS voltage;
* Check/adjust minimum air rate;
* Check/adjust timing;
* Code scan;

If you are performing Scheduled Service based on usage or mileage, the service items will be different.
