Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench
Remove the engine cover if applicable.
Use the socket to remove the old spark plugs.
Inspect the old spark plugs for signs of wear or fouling.
Install new spark plugs, ensuring they are torqued to the manufacturer's specifications (usually around 13-15 lb-ft).
Reattach the engine cover.

3. Check and Replace Ignition Coils

Tools Required: Socket set
Disconnect the electrical connectors from the ignition coils.
Remove the bolts securing the ignition coils and pull them out gently.
Inspect for signs of damage or wear.
Install new ignition coils and reconnect the electrical connectors.

4. Clean or Replace MAF Sensor

Tools Required: Torx screwdriver, MAF cleaner
Remove the electrical connector from the MAF sensor.
Unscrew and remove the MAF sensor from the air intake duct.
Clean using MAF sensor cleaner and a lint-free cloth or replace if necessary.
Reinstall the MAF sensor and reconnect the electrical connector.

5. Check Fuel System

Tools Required: Fuel pressure gauge
Connect the fuel pressure gauge to the fuel rail according to the vehicle manual.
Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading.
If pressure is low, inspect the fuel filter and fuel pump for issues. Replace any necessary components.
