Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuel Filter

Sub-steps:
1. Locate the fuel filter (usually along the fuel line).
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, using appropriate line wrenches to avoid damage.
4. Remove the old fuel filter and replace it with a new one, ensuring correct orientation.
5. Reconnect fuel lines securely.
Tools Required: Line wrenches, safety glasses, gloves.

3. Test and Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover if necessary to access the ignition coils.
2. Disconnect the electrical connectors from the ignition coils.
3. Unscrew the coils and remove them along with the spark plugs.
4. Inspect the spark plugs for wear; replace if necessary (gapped to manufacturer specifications).
5. Install new ignition coils and reconnect them.
Tools Required: Socket set, torque wrench, spark plug gap tool.

4. Clean Throttle Body

Sub-steps:
1. Disconnect the air intake hose from the throttle body.
2. Use throttle body cleaner and a soft cloth or brush to clean the throttle body surface.
3. Ensure the throttle plate operates smoothly without sticking.
4. Reattach the air intake hose securely.
Tools Required: Throttle body cleaner, soft cloth, screwdriver.

5. Check Battery and Alternator

Sub-steps:
1. Use a multimeter to measure the voltage at the battery terminals (should be around 12.6 volts).
2. Start the engine and measure the voltage again (should be between 13.7 to 14.7 volts).
3. Replace the battery or alternator if voltage readings are outside these ranges.
Tools Required: Multimeter.
