Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Components

A. Air Filter

Remove the air filter housing using a socket set.
Take out the air filter and inspect for dirt or blockages.
Clean or replace the air filter if necessary.

B. Throttle Position Sensor (TPS)

Locate the TPS on the throttle body.
Disconnect the electrical connector and remove the mounting screws.
Clean the sensor with electrical contact cleaner.
Reinstall the TPS and reconnect the electrical connector.

C. Mass Air Flow (MAF) Sensor

Locate the MAF sensor in the air intake duct.
Disconnect the electrical connector and remove the sensor.
Clean the MAF sensor using MAF cleaner spray.
Reinstall the MAF sensor and reconnect the electrical connector.

3. Inspect the Ignition System

Remove the ignition coil cover and inspect the ignition coils.
Check the spark plugs for wear or fouling and replace if necessary.
Reinstall components and connect all wiring securely.

4. Fuel System Check

Check the fuel pressure using a fuel pressure gauge.
If pressure is low, inspect the fuel pump and fuel filter for issues and replace as needed.

5. Final Assembly

Reconnect the battery and ensure all components are secure.
Start the engine and let it idle to ensure everything is functioning properly.
