Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool if it has been running.

2. Clean the Throttle Body

Remove the engine cover if applicable.
Disconnect the throttle body connector.
Unbolt and remove the throttle body from the intake manifold.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Reinstall the throttle body and reconnect the electrical connector.

3. Inspect and Replace Spark Plugs

Remove the engine cover if necessary to access the spark plugs.
Disconnect the ignition coil connectors.
Remove the ignition coils and inspect for damage.
Use a spark plug socket to remove the spark plugs.
Check the gap on the new spark plugs and replace if necessary.
Reinstall the spark plugs and ignition coils.

4. Fuel System Check

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (do not start the engine) to read the pressure.
If the pressure is below specifications, inspect/replacement may be needed for the fuel pump or fuel filter.
Reinstall any components removed during the process.

5. Inspect Air Intake System

Check the air filter for dirt and debris; replace if necessary.
Inspect the intake duct for tears or loose connections.
Ensure the Mass Air Flow (MAF) sensor is clean; use MAF cleaner as needed.
