Solution

1. Preparation

Gather tools and parts necessary for the repair.
Disconnect the negative battery terminal to ensure safety.

2. Clean or Replace Throttle Body

Tools Required: Throttle body cleaner, soft brush, socket set, and torque wrench.
Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Disconnect the throttle body electrical connector.
3. Remove the throttle body mounting bolts and take out the throttle body.
4. Clean the throttle body using throttle body cleaner and a soft brush.
5. If severely damaged or faulty, replace with a new throttle body.
6. Reinstall the throttle body and reconnect the electrical connector.
7. Reattach the air intake duct and secure it properly.

3. Inspect Fuel System

Tools Required: Fuel pressure gauge, socket set.
Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Attach the fuel pressure gauge and turn the ignition to the "On" position (do not start the engine) to check fuel pressure.
3. If pressure is low, inspect the fuel pump and fuel filter, replacing them if necessary.
4. Ensure the fuel lines are secure and free from leaks.

4. Check Ignition System

Tools Required: Spark plug socket, multimeter.
Sub-steps:
1. Remove the spark plugs and inspect for wear or damage.
2. Measure the resistance of the ignition coils with a multimeter to ensure they are within specifications.
3. Replace any faulty spark plugs or ignition coils.

5. Final Check and Reassembly

Ensure all components are securely fastened and all connections are made.
Reconnect the negative battery terminal.
