Solution

1. Preparation

Gather tools and materials, including an OBD-II scanner, fuel pressure gauge, cleaning supplies, and replacement parts as needed.
Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Instructions:
1. Disconnect the negative battery terminal to ensure safety.
2. Remove the air intake duct to access the throttle body.
3. Open the throttle plate manually and spray throttle body cleaner inside using a soft cloth to wipe away carbon deposits.
4. Reconnect the air intake duct and the negative battery terminal.

3. Check and Replace the Fuel Filter (if necessary)

Tools Required: Socket set, fuel line disconnect tool, replacement fuel filter.
Instructions:
1. Relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
2. Disconnect the fuel lines from the fuel filter using the fuel line disconnect tool.
3. Remove the old fuel filter and install the new one, ensuring the flow direction matches the original.
4. Reconnect the fuel lines and reinsert the fuel pump fuse.

4. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, new spark plugs.
Instructions:
1. Remove the engine cover if applicable to access the spark plugs.
2. Disconnect the ignition coil connectors and remove the coils using the socket set.
3. Remove the old spark plugs with a spark plug socket and inspect them for wear.
4. Install new spark plugs, tightening them to the manufacturer's specified torque.
5. Reinstall the ignition coils and connect the electrical connectors.
