Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to ensure safety during repairs.

2. Inspect Fuel System

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Connect a fuel pressure gauge to the test port.
3. Turn the ignition to the "ON" position (do not start the engine) and check fuel pressure readings against manufacturer specifications (usually around 40-50 PSI).
4. If pressure is low, replace the fuel pump and/or fuel filter.

Tools Required:

Fuel pressure gauge
Wrench set

3. Clean Throttle Body

Sub-steps:
1. Remove the air intake duct connecting to the throttle body.
2. Use throttle body cleaner and a clean cloth to remove carbon buildup inside the throttle body.
3. Reinstall the air intake duct securely.

Tools Required:

Throttle body cleaner
Screwdrivers

4. Check Ignition System

Sub-steps:
1. Remove spark plugs using a spark plug socket.
2. Inspect each plug for wear or fouling; replace if necessary with OEM specifications.
3. Check ignition coils for damage or malfunction; replace any faulty coils.

Tools Required:

Spark plug socket
Torque wrench (for spark plug installation)
