Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge, vacuum gauge.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts while working on the vehicle.

2. Check and Replace Fuel Components

Fuel Pump and Filter:
1. Remove the rear seat or access panel to locate the fuel pump assembly.
2. Disconnect the fuel lines and electrical connector from the pump.
3. Remove the retaining ring and carefully lift out the fuel pump.
4. Inspect the fuel filter; replace if clogged or damaged (follow service manual for specifications).
5. Reinstall the new fuel pump and filter, reconnecting all lines and the electrical connector.

3. Inspect and Replace Ignition Components

Spark Plugs and Ignition Coils:
1. Remove the engine cover to access the ignition coils.
2. Disconnect the electrical connectors from each ignition coil.
3. Remove the bolts securing the ignition coils and lift them out.
4. Inspect spark plugs for wear; replace if necessary (check gap specifications).
5. Install new ignition coils and reconnect the electrical connectors.

4. Test and Replace Sensors

Throttle Position Sensor (TPS) and Mass Airflow Sensor (MAF):
1. Locate the TPS and MAF on the throttle body and air intake respectively.
2. Disconnect the electrical connectors.
3. Use a multimeter to measure the resistance across the TPS terminals; replace if it does not meet specifications.
4. Clean the MAF with appropriate cleaner, ensuring no residue remains.
5. Reinstall the sensors and reconnect the electrical connectors.

5. Inspect Vacuum Lines

Check all vacuum lines for cracks or loose connections.
Replace any damaged lines to ensure proper engine vacuum.
