Solution

1. Preparation

Gather tools and parts needed for repair.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt or damage.
Replace it with a new, manufacturer-recommended air filter.
Reassemble the air filter housing cover.

3. Fuel System Inspection

Locate the fuel pump relay and fuse in the fuse box; check for proper operation.
If necessary, replace the fuel filter and inspect fuel lines for leaks or blockages.
Use a fuel pressure gauge to check the fuel pressure against manufacturer specifications.

4. Exhaust System Check

Visually inspect the exhaust system for any signs of damage or blockage.
If the catalytic converter is suspected to be clogged, remove it for inspection.
Replace the catalytic converter if necessary, adhering to torque specifications during reinstallation.

5. Throttle Position Sensor Adjustment

Locate the throttle position sensor on the intake manifold.
Disconnect the electrical connector and remove the sensor using a Torx screwdriver.
Clean the mounting surface and install a new throttle position sensor.
Reconnect the electrical connector and reset the engine control unit (ECU) if needed.
