Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, cleaning supplies.
Ensure the vehicle is parked on a flat surface and the engine is turned off. Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Sub-steps:
- Open the hood and locate the air filter housing.
- Remove the screws or clips securing the housing and take it apart.
- Remove the old air filter and inspect it for dirt and damage.
- Replace with a new air filter if necessary (use OEM or equivalent).
- Reassemble the air filter housing, securing it properly.

3. Fuel System Inspection

Sub-steps:
- Locate the fuel pressure test port on the fuel rail.
- Attach a fuel pressure gauge and start the engine to measure fuel pressure.
- If pressure is low, inspect the fuel pump and filter for clogs or malfunction.
- Replace the fuel filter if clogged, and consider replacing the fuel pump if it does not maintain proper pressure.

4. Throttle Body Cleaning

Sub-steps:
- Locate the throttle body by following the air intake duct.
- Disconnect the throttle position sensor harness and any vacuum lines connected.
- Remove the throttle body from the intake manifold (take note of the torque specifications for reinstallation).
- Clean the throttle body using a throttle body cleaner and a soft brush or cloth.
- Reinstall the throttle body, reconnecting all sensors and vacuum lines.

5. Spark Plug and Ignition System Check

Sub-steps:
- Remove the spark plug wires or coils, noting their positions.
- Remove the spark plugs using a socket wrench and inspect them for wear or carbon buildup.
- Replace any worn spark plugs with OEM recommended plugs and ensure proper gap.
- Reconnect the spark plug wires or coils securely.
