Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, basic hand tools
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during repairs.

2. Addressing Fuel Pressure Issues

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail service port.
2. Turn the ignition to the "ON" position (do not start) and check the fuel pressure reading.
3. If pressure is below specifications, inspect the fuel pump and filter for blockages or failures.
4. Replace the fuel filter if it appears clogged or dirty.
5. If necessary, replace the fuel pump, ensuring proper alignment and secure connections.

3. Ignition System Inspection and Replacement

Sub-steps:
1. Remove the engine cover (if applicable) to access the ignition components.
2. Disconnect the spark plug wires or coils from the spark plugs.
3. Remove the spark plugs using a socket wrench and inspect them for wear (look for carbon buildup or electrode wear).
4. Replace spark plugs with OEM specifications, ensuring proper gap settings.
5. Reconnect the ignition coils or spark plug wires.

4. Air Intake System Check

Sub-steps:
1. Inspect the air filter for dirt or blockages and replace it if necessary.
2. Check the intake manifold and hoses for any signs of leaks or cracks.
3. Clean the throttle body using a throttle body cleaner to remove carbon deposits.
4. Reassemble any components removed during inspection.

5. Exhaust System Inspection

Sub-steps:
1. Visually inspect the exhaust system for any signs of damage or leaks.
2. Use a smoke test to identify hidden leaks in the exhaust system.
3. Replace any damaged catalytic converters or exhaust pipes as necessary.
