Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect and Clean the Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body using a socket set.
2. Disconnect any electrical connectors or sensors attached to the throttle body.
3. Remove the throttle body from the intake manifold by unscrewing the bolts (use a torque wrench for accuracy).
4. Clean the throttle body using throttle body cleaner and a soft cloth, ensuring all carbon deposits are removed.
5. Reinstall the throttle body in reverse order and torque the bolts to the manufacturer's specifications.

3. Check and Replace Spark Plugs (if necessary)

Sub-steps:
1. Remove the ignition coil from the cylinder head by unscrewing the bolts.
2. Carefully pull out the spark plug using a spark plug socket.
3. Inspect the spark plug for wear or damage; replace with new plugs if necessary, ensuring the gap is set to manufacturer specifications.
4. Reinstall the ignition coil and secure it with bolts.

4. Inspect Fuel System

Sub-steps:
1. Check the fuel filter for clogs and replace it if necessary.
2. If the fuel pump is suspected to be malfunctioning, test the fuel pressure using a fuel pressure gauge.
3. Replace the fuel pump if it is not delivering adequate pressure.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle, checking for any remaining issues.
