get a spray bottle and fill it with
soapy water. Start the engine and systematically start spraying the

I will assume it is a 2.5 liter. The control module is bolted to the back of the block underneath the intake manifold. The assembly incorporates the crank sensor, module and coils. Just follow the spark plug wires and you will find it.
If you are referring to a "tune-up", then for a complete tune-up for your vehicle you will need to replace the ignition wires (spark plug wires), spark plugs, air filter, the fuel filter, and also the pcv valve. There is no distributor in your vehicle so that is all that a complete tune-up for your vehicle will consist of. Here is a firing order diagram for both engines that were available for that vehicle to help assist you replace the ignition wires, and let me know if you require any further assistance.

To get the most accurate diagrams, purchase a Chilton's, or Haynes manual for your car. They have ALL of the wiring diagrams for every system of your vehicle and they're very easy to follow. The books can be purchased online, or at most auto parts stores for around $15
