Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.
Wear safety goggles and gloves.

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 and obstructions.
Clean the housing with a damp cloth.
Install a new air filter, ensuring it fits snugly, then reattach the housing cover.

3. Check and Repair Fuel System

Inspect fuel lines and connections for visible leaks.
If leaks are found, replace damaged fuel lines using appropriate replacement parts.
Test fuel injectors for proper spray pattern using a multimeter; replace if faulty.

4. Examine and Replace Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove the mounting screws.
Install the new throttle position sensor and reconnect the electrical connector.
Reset the engine control module (ECM) by reconnecting the battery.

5. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire’s pressure.
Inflate tires to the manufacturer’s recommended pressure listed on the driver’s door jamb.
