Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working.

2. Inspect and Replace Air Filter

Locate the air filter housing and remove the cover.
Take out the old air filter and inspect it for dirt and blockages.
Install a new, clean air filter.
- Tools Required: Flathead screwdriver or socket set (if needed for the housing)

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine to check fuel pressure.
If pressure is below manufacturer specifications, replace the fuel pump.
- Tools Required: Fuel pressure gauge, socket set, safety glasses, rags
- Safety Warning: Relieve fuel system pressure before disconnecting fuel lines.

4. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Ensure that the throttle plate opens smoothly and is not sticking.
- Tools Required: Throttle body cleaner, soft cloth, socket set

5. Spark Plug and Ignition Coil Replacement

Remove the ignition coil covers (if applicable) and disconnect the electrical connectors.
Remove the old ignition coils and spark plugs using a socket wrench.
Install new spark plugs, ensuring they are gapped correctly to manufacturer specifications.
Reinstall the ignition coils and covers.
- Tools Required: Socket set, torque wrench (for spark plugs), gap tool

6. MAF Sensor Cleaning

Disconnect the MAF sensor connector and remove the sensor from the intake.
Spray MAF sensor cleaner on the sensor element, avoiding contact with other components.
Allow it to dry before reinstalling the sensor.
- Tools Required: MAF sensor cleaner, socket set
