Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspect and Replace Air Filter

Sub-steps:
- Open the hood and locate the air filter housing.
- Remove the clips or screws holding the housing in place.
- Take out the old air filter and inspect it for dirt and blockages.
- Install a new, clean air filter (OEM or recommended equivalent).
- Reassemble the air filter housing securely.

3. Check Tire Pressure and Condition

Sub-steps:
- Use a tire pressure gauge to check the pressure of all four tires.
- Inflate tires to the recommended PSI as stated in the owner’s manual.
- Inspect tires for uneven wear or damage; replace if necessary.

4. Fuel Quality Inspection

Sub-steps:
- Verify the fuel level in the tank.
- If fuel is old or potentially contaminated, drain the tank and refill with fresh, high-quality fuel.

5. Test Throttle Position Sensor (TPS)

Sub-steps:
- Locate the throttle body and TPS.
- Connect a multimeter to the TPS terminals as per service manual specifications.
- Check voltage readings while manually operating the throttle; ensure they fall within the specified range.
- If readings are outside specifications, replace the TPS.
