Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge, and cleaning supplies.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Check and Replace Battery

Sub-steps:
1. Use a multimeter to check the battery voltage (should be around 12.6 volts when off).
2. If voltage is low, charge or replace the battery.
3. Inspect battery terminals for corrosion; clean if necessary.
4. Tighten any loose connections.

3. Inspect and Replace Fuel Filter

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 using appropriate tools.
4. Replace the filter with a new one, ensuring correct orientation.
5. Reconnect fuel lines and install the fuse.

4. Clean or Replace Throttle Body

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove the air intake duct to access the throttle body.
3. Use throttle body cleaner and a soft cloth to remove carbon buildup.
4. If severely damaged, replace the throttle body with a new one.
5. Reinstall the air intake duct and reconnect the battery terminal.

5. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the ignition coil covers (if applicable) and disconnect the coils.
2. Remove the old spark plugs using a socket wrench.
3. Install new spark plugs, ensuring the gap is set according to manufacturer specifications.
4. Reinstall ignition coils and covers.
