Not exactly sure what you need?
Standard Rules:
Use a Spark Plug Socket to remove and install Spark Plugs.
Replace (remove) one Wire at a time from one Spark Plug.
Replace One Spark Plug at a time. Use Anti-Seize Grease applied moderately to the threads on the new Spark Plug.
Using a Socket (with a extension) START all installations using your hands. This prevents cross-threading and stripping of the threads inside the Heads.
Standard Torque 15-20 ft-lbs.
Replace the One Wire connection to that One Spark Plug.
Replace that One Wire connection to the Ignition Coil.
Go onto the next Spark Plug using the above Rules.
Repeat.

You have a Misfire at Cylinder #4 meaning:
Dirty, fouled or malfunction Spark Plug at #4 Cylinder. Remove the Spark Plug and check the igntion (spark end).
Ignition (Spark Plug) Wire malfunction for #4 Cylinder.
Misfire from the Coil/Distributor at the #4 connection from Cylinder #4.
Get a Spark Plug/Wire/Coil/Distributor tester and check the Spark Plug, Wire and Coil.
I always recommend changing everything in sets meaning: Change all Spark Plugs and Wires.

I really hope help you with this (remember rated this help) Good luck.

You didn't specify whether you have the (4) cylinder or the (6) cylinder engine..... I have a 2004 Hyundai Sonata 2.4L 4 cylinder and I just changed the spark plugs in it. I believe that the 2005 2.4L engine is the same. To locate and change the (4) spark plugs on a 2004 Hyundai 2.4L 4 cylinder engine: Remove the (4) 12mm bolts from the decorative plastic engine cover. Remove plastic cover from engine and place it off to the side out of your way. Standing in front of the car, the (4) spark plugs are located laterally (left to right) in the recessed area underneath where the plastic engine cover was removed. Note: This engine has (2) coils....They are located above spark plugs number (2) and (3) from left to right. Starting with the fist spark plug on the left: Remove the spark plug cable by pulling straight up on the insulated connector. Using a spark plug socket, remove the old spark plug and install a new one in it's place. To access the second spark plug from the left, remove the electrical connector and the spark plug cable wire from coil number (1) and then remove the (2) 12mm bolts that secure the coil to the engine. Spark plug number (2) is located directly under the coil. Lift the coil straight up removing the insulated connector from spark plug number (2). Using a spark plug socket, remove old spark and install a new one in it's place. Repeat same procedures for spark plugs number (3) and (4). Note: If you have the (6) cylinder engine, the front (3) sparks pluge are readilly accessible but in order to access the (3) rear spark plugs, you will have to remove the intake manifold

4 plugs in the front 4 in the back it is necessary toi remove some components to gain access to the rear bank of plugs
