Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter.
Clear the engine bay and ensure the vehicle is on a level surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if applicable.
2. Unscrew and detach the ignition coils from the spark plugs.
3. Using a socket wrench, carefully remove the spark plugs.
4. Inspect the old spark plugs for wear; if they are fouled, replace with OEM recommended spark plugs.
5. Gap the new spark plugs according to the specifications and install them.
6. Reattach the ignition coils, ensuring they click into place.

3. Check and Replace Fuel Filter (if applicable)

Sub-steps:
1. Locate the fuel filter; refer to the service manual for specific location.
2. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
3. Disconnect the fuel lines from the filter, taking care to collect any spilled fuel.
4. Remove the old fuel filter and install the new one in the correct orientation.
5. Reconnect the fuel lines securely and reinstall the fuel pump fuse.

4. Inspect and Replace Air Filter

Sub-steps:
1. Open the hood and locate the air intake box.
2. Unclip or unscrew the air intake box cover to access the air filter.
3. Remove the old air filter and inspect for dirt or blockages.
4. Install a new air filter that meets OEM specifications.
5. Reassemble the air intake box cover, ensuring it is sealed properly.

5. Test and Replace Ignition Coils (if necessary)

Sub-steps:
1. Use a multimeter to test the ignition coils for resistance; compare readings with specifications.
2. If any coils are faulty, disconnect them and remove the mounting bolts.
3. Install new ignition coils in place of the old ones, ensuring proper connections.
4. Reattach any wiring harnesses and ensure they are secured.
