Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shock.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, socket set, safety goggles
Remove the fuel pump fuse from the fuse box.
Use the fuel pressure gauge to connect to the fuel rail test port.
Turn the ignition key to the "ON" position (do not start the engine) and observe the pressure reading; it should meet manufacturer specifications.
If pressure is low, check the fuel filter for clogs; replace if necessary.
Reinstall the fuel pump fuse.

3. Ignition System Repair

Tools Required: Socket set, torque wrench, replacement spark plugs and ignition coils
Remove the engine cover if applicable.
Disconnect the ignition coil connectors and remove the bolts securing the ignition coils.
Remove the spark plugs using a socket wrench; inspect for wear or fouling.
Replace the spark plugs with new ones, ensuring they are gapped to manufacturer specifications.
Reinstall the ignition coils, tightening to the specified torque.

4. Vacuum Leak Inspection and Repair

Tools Required: Vacuum gauge, hose clamps, replacement hoses
Start the engine and use a vacuum gauge to measure the manifold vacuum; abnormal readings may indicate a leak.
Inspect vacuum lines for cracks or disconnections; replace any damaged hoses.
Reconnect any disconnected hoses securely.
