Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shorts.

2. Replace Fuel Filter

Tools Required: Wrench set, fuel line removal tool, safety glasses, and gloves.
Sub-steps:
1. Locate the fuel filter; it is typically found along the fuel line under the vehicle.
2. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
3. Disconnect the fuel lines using a fuel line removal tool.
4. Remove the mounting bolts securing the fuel filter and take it out.
5. Install the new fuel filter in the same orientation as the old one and secure it with the mounting bolts.
6. Reconnect the fuel lines, ensuring they are secure.

3. Inspect and Clean Throttle Body

Tools Required: Throttle body cleaner, soft brush, and rags.
Sub-steps:
1. Remove the air intake duct leading to the throttle body.
2. Use throttle body cleaner and a soft brush to clean the inside of the throttle body, removing carbon buildup.
3. Wipe the area clean with a rag.
4. Reattach the air intake duct securely.

4. Test and Replace Ignition Components

Tools Required: Multimeter, socket set, and torque wrench.
Sub-steps:
1. Remove the ignition coils and inspect them for cracks or damage.
2. Use a multimeter to test the resistance of the spark plugs and ignition coils, comparing readings to manufacturer specifications.
3. Replace any faulty spark plugs or ignition coils as necessary.
4. Reinstall the ignition components and torque them to manufacturer specifications.
