Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, multimeter, socket set, and safety goggles.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Fuel Delivery Issues

Check Fuel Pressure:
1. Connect the fuel pressure gauge to the fuel rail test port.
2. Turn the ignition to the "ON" position (do not start) and observe the gauge reading. It should typically be between 40-50 psi.
3. If the pressure is low, inspect the fuel pump, fuel filter, and fuel lines for blockages or failures.
Replace Fuel Filter (if necessary):
1. Locate the fuel filter under the vehicle.
2. Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
3. Disconnect the fuel lines from the filter (use caution to avoid fuel spray).
4. Remove the old filter and install a new one, ensuring correct orientation.
5. Reconnect the fuel lines and reinstall the fuel pump fuse.

3. Inspect and Replace Ignition Components

Inspect Spark Plugs and Coils:
1. Remove the engine cover if applicable.
2. Disconnect the ignition coil connectors and remove the coils using a socket set.
3. Inspect the spark plugs for wear, fouling, or damage. Replace if necessary.
4. Install new spark plugs, tightening to the manufacturer's specified torque (typically around 13-15 lb-ft).
5. Reinstall the ignition coils and reconnect the connectors.

4. Check for Vacuum Leaks

Inspect and Repair Vacuum Hoses:
1. Visually inspect all vacuum hoses connected to the intake manifold.
2. Use a smoke machine or carburetor cleaner to identify leaks while the engine is running.
3. Replace any cracked or damaged hoses and ensure all connections are secure.
