Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Air Intake System

Remove the air filter and inspect for dirt and debris.
Clean the air intake duct and throttle body using throttle body cleaner.
Reinstall the air filter or replace it if necessary.

3. Check and Replace Fuel Filter

Locate the fuel filter; relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter, and remove the old filter.
Install the new fuel filter, ensuring proper orientation and secure connections.
Reinstall the fuel pump fuse and check for leaks.

4. Test and Replace Throttle Position Sensor (if faulty)

Disconnect the connector from the throttle position sensor.
Use a multimeter to test the sensor's resistance; refer to the vehicle’s specifications for correct values.
If out of specification, replace the sensor with a new unit and reconnect.

5. Inspect and Replace Ignition Components

Remove spark plug wires and inspect for wear or damage; replace if necessary.
Remove spark plugs and inspect for wear; replace with OEM specifications.
If ignition coils are suspected, test them with a multimeter or replace them as needed.
