Did not say what size engine, you could have a 2.3L 4 cylinder or a 3.1L 6 cylinder, so here's both, hope this was very helpful.

Need to know how to change plugs & plug wires on

If you have a distributor or just an ignition module with
plug wires, you not only mark them with a ball point pen,
you make a drawing of where things are

You can see the spark plugs,mark both ends of the plug wires
before you start

Draw a picture of the cylinders & look up their numbers
& write it in little circles & have the firing order

The only problem you can have is not knowing what is where,
before you start, so you can replace old or new parts where they
should go

How to change the spark plugs and wires

First you need to research your Make and Model vehicle and determine your spark plug size (5/8 or or larger) typically there are only 3 sizes but you'll need to know which as you will have to buy the Spark plug socket to remove them. Next you need to locate a online diagram or Haynes Manual to see if you yourself can reach or change the plugs and wires as some cars are built in such a way that only a Technician would know how to reach them properly. 3rd you will need to determine if the OEM wires (Original Equipment Manuafacturer) part is available (cheaper) or if you will have to buy a aftermarket set (Bosch or ACCEL). Removing plugs will require a Socket wrench, spark plug socket and extension. when putting in new plugs make sure you use Anti-sieze on the thread of the new plugs before installation (keeps from locking up into the head) also make sure you use Plug wire boot lubrication before putting in new wires (this helps make sure that future plug replacement is easy as it will help the boot slide on and off. That's it without knowing your exact make and model.
