Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge, torque wrench.
Ensure the vehicle is parked on a flat surface with the engine off and cool.
Disconnect the battery to ensure safety during electrical inspections.

2. Fuel System Inspection

Check Fuel Pressure:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position (without starting) and note the pressure reading.
3. Compare the reading to the manufacturer's specifications (typically 40-50 psi).
4. If low, inspect the fuel pump and filter for clogs or faults.
Replace Fuel Filter:
1. Locate the fuel filter (usually near the fuel tank or along the fuel line).
2. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
3. Disconnect the fuel lines from the filter using a special tool if necessary.
4. Install the new filter, ensuring the flow direction is correct.
5. Reconnect the fuel pump fuse and check for leaks.

3. Ignition System Repair

Inspect and Replace Spark Plugs:
1. Remove spark plug wires using a spark plug socket.
2. Inspect each spark plug for wear, carbon buildup, or damage.
3. Replace with new OEM spark plugs if necessary, ensuring proper gap settings (typically 0.044 inches).
Check Ignition Coils:
1. Disconnect the electrical connector from each ignition coil.
2. Use a multimeter to measure resistance; compare with specifications (usually between 0.4 to 2.0 ohms).
3. Replace any faulty coils with OEM parts.

4. Air Intake System Inspection

Clean or Replace Air Filter:
1. Locate the air filter box and remove the cover.
2. Inspect the air filter for dirt and debris; clean or replace as needed.
Inspect for Vacuum Leaks:
1. Visually inspect hoses connected to the intake manifold for cracks or disconnections.
2. Use a smoke machine or carburetor cleaner to check for leaks while the engine is running.
