You will need a special tool to safely pull the spark plug boots off the plugs. You can buy one on eBay or Amazon, or you can make one from a bent 17mm open-end wrench.
Do some research on the plugs that you need - 16 of them, platinum or iridium, possibly Bosch.

Be very careful with crispy vacuum lines and wire jackets.

Learn how to raise the hood to the straight-up service position.

It would be really nice to have access to SDS (STAR Diagnostic System) so you could read all of the trouble codes, current or stored. An OBD-II code reader is not what you need - only SDS.
