Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shock.

2. Replace Clogged Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits snugly.
Reattach the housing cover and tighten screws to manufacturer specifications.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) and check pressure readings.
If pressure is low, inspect the fuel pump and replace if necessary.
Disconnect the gauge and safely reconnect fuel lines.

4. Inspect and Replace Ignition Components

Remove ignition coil covers using a socket set.
Check spark plugs for wear; if necessary, remove and replace with OEM specifications.
Reinstall coils and covers, ensuring all connections are secure.

5. Clean Throttle Body

Remove the throttle body from the intake manifold by disconnecting the electrical connector and unscrewing the mounting bolts.
Use throttle body cleaner and a soft brush to clean carbon buildup.
Reinstall the throttle body, ensuring a proper seal and reconnecting the electrical connector.

6. Test and Replace MAF Sensor (if necessary)

Disconnect the MAF sensor's electrical connector.
Remove the sensor from the air intake duct.
Inspect for contamination; clean if dirty or replace with a new sensor.
Reinstall the MAF sensor and reconnect the electrical connector.
