Tisn't quite like just screwing in four plugs mate! Parts could be $100 just for plugs and insulators so if that's your limit for 100k service with a rough idle you're in trouble! See below as an idea,

~~~~~~~~~~~~~~~~~~~~~~~~~~~~
REMOVAL & INSTALLATION
2.4L Engine
- Disconnect the negative battery cable.
- Detach the Ignition Control Module (ICM) harness connector.
- Remove the accelerator and cruise control cables from the hold-down clip.
- Remove the fuel line retainer clip bolt.
 Exploded view of the ignition coil and ICM on the 2.4L engine. Note the location of the contact springs between the housing and spark plug boots  Detach the harness connector, which is located at the end of the ignition component cover - Remove the four ICM cover bolts.
 The ICM cover is secured with four retaining bolts NOTE Be sure to check each boot for the spring, located inside the boot. If any springs are missing, replace before reinstalling. - Gently lift the ICM cover up off of the spark plugs. Some boots and retainers may pull off of the ignition coil housing, this is not unusual, simply replace them during installation.
NOTE If the boots stick to the spark plugs, using a spark plug boot remover tool or soft-jawed pliers, remove by first twisting, then carefully pulling upward on the retainers. Reinstall the boots and retainers on the ignition coil housing secondary terminals. The boots and retainers must be in place on the ignition coil housing prior to installation or damage to the ignition system could result.  The spark plug boots and retainers may pull off of the housing assembly. Simply replace before installation - Remove the housing-to-cover screws.
NOTE When removing the housing from the cover screws, make sure the ground strap stays in place.  Remove the ignition coil housing-to-cover screws  Disconnect the ICM harness connector after separating the coils from the module - Separate the Ignition Control Module (ICM) housing assembly from the ignition coils.
- Detach the ICM harness connector from the ignition coils.
- Unplug the electrical connector from the ignition coil.
 This connector is to be disengaged if the coils are to be separated - Remove the contact springs from the housing.
- Remove the ignition coil seals from the coils.
 The contact springs are replaced when a new coil is installed. Make sure new contact springs come with the coil  The coil seals are removed for testing and inspection
To install: - Install the ignition coil seals to the coils.
- Install the contact springs to the housing.
- Connect the ignition coils to the ICM wiring harness.
- Gently place the ignition coils into the housing assembly.
NOTE When installing the housing, make sure the ground strap is in place.  The ground strap must be in place before the housing bolts are installed and tightened - Fasten the housing bolts and tighten to 35 inch lbs. (4 Nm).
- Connect the spark plug boots and retainers to the housing.
- Install the assembly to the engine, while carefully aligning the spark plugs to the spark plug boots.

Not much is like the old days. Four stupid plugs can be a nightmare but give it credit - we used to change them Spring and Fall back when too - not just every 10 years!
Best to stay at the bar sometimes.....
