Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, basic hand tools
Disconnect the negative battery terminal to prevent electrical shorts during repairs.
Ensure the vehicle is parked on a flat surface with the engine turned off and cooled down.

2. Check Fuel System

Sub-steps:
1. Locate the fuel pump access panel (if applicable) or lift the vehicle safely to access the fuel tank.
2. Use a fuel pressure gauge to check the fuel pressure. Refer to the service manual for the correct pressure specifications.
3. If pressure is low, inspect the fuel pump and fuel filter for clogs or failures. Replace if necessary.

3. Inspect Ignition System

Sub-steps:
1. Remove the spark plug wires and inspect for damage.
2. Use a spark plug socket to remove the spark plugs and check for wear or deposits.
3. Replace any worn or damaged spark plugs with OEM-recommended parts, ensuring proper torque specifications (usually around 12-15 ft-lbs).

4. Clean Throttle Body and MAF Sensor

Sub-steps:
1. Disconnect the air intake duct from the throttle body and remove it.
2. Use throttle body cleaner to spray and wipe down the throttle body. Ensure the butterfly valve moves freely.
3. Disconnect the mass airflow sensor and clean it using MAF sensor cleaner. Let dry completely before reinstallation.

5. Reassemble and Test

Sub-steps:
1. Reconnect all components removed during inspection.
2. Reconnect the negative battery terminal.
3. Start the engine and let it idle to check for any irregularities.
