Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Fuel System Check

2.1 Inspect Fuel Pump

Locate the fuel pump access panel (if applicable) or remove the fuel tank.
Use a fuel pressure gauge to check fuel pump operation. Refer to the manufacturer specifications for correct pressure readings.
If the pressure is low, replace the fuel pump.

2.2 Replace Fuel Filter

Locate the fuel filter (usually along the fuel line).
Relieve fuel system pressure before removal.
Disconnect fuel lines and remove the old filter.
Install the new filter, ensuring proper orientation, and reconnect the lines.

3. Ignition System Inspection

3.1 Check Spark Plugs

Remove the spark plug wires and then the spark plugs using a socket wrench.
Inspect the plugs for wear, carbon buildup, or damage. Replace if necessary.
Reinstall the new or cleaned spark plugs with the specified torque (typically around 13-15 ft-lbs).

3.2 Inspect Ignition Coils

Remove the ignition coils from their respective cylinders.
Check for cracks or damage. Replace any faulty coils.

4. Throttle Body Cleaning

Remove the air intake duct to access the throttle body.
Use throttle body cleaner to clean the throttle plate and surrounding area.
Reassemble the intake duct and ensure all clamps are secure.

5. Final Checks

Reconnect the negative battery terminal.
Start the vehicle and allow it to idle, checking for any irregularities.
