Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts during the process.

2. Inspect and Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench, gap tool.
Remove the ignition coil cover if applicable.
Use the spark plug socket to carefully remove each spark plug.
Inspect each spark plug for signs of wear, carbon deposits, or damage.
If needed, replace with new spark plugs, ensuring the gap is set to manufacturer specifications.
Torque the spark plugs to the specified value (usually around 15-20 ft-lbs).

3. Check and Replace Fuel Filter

Tools Required: Fuel line disconnect tool, wrench set, container for fuel spillage.
Locate the fuel filter in the fuel line.
Use the fuel line disconnect tool to carefully disconnect fuel lines from the filter.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and check for leaks.

4. Clean or Replace Fuel Injectors

Tools Required: Injector cleaning kit or replacement injectors.
If cleaning, follow the instructions provided with the injector cleaning kit to remove carbon deposits.
If replacing, carefully remove each injector from the fuel rail, noting the orientation.
Install new injectors and ensure they are seated properly.

5. Reassemble and Test

Reinstall any components removed during the process.
Reconnect the negative battery terminal.
Start the engine and allow it to reach operating temperature, monitoring for improvements in performance.
