Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during electrical inspections.

2. Check and Replace Fluids

Engine Oil:
- Drain old engine oil using an oil drain pan.
- Replace with the manufacturer-recommended oil type and viscosity.
- Replace the oil filter.
- Torque the oil drain plug to the manufacturer’s specification.
Transmission Fluid:
- Locate the transmission fluid dipstick and check the level and condition.
- If low or dirty, drain the transmission fluid using a fluid catch pan.
- Refill with the appropriate transmission fluid type as specified in the owner's manual.

3. Inspect and Replace Air Filter

Open the hood and locate the air filter housing.
Remove the air filter cover by unscrewing or unclipping it.
Inspect the air filter; if dirty, replace it with a new one.
Reassemble the air filter housing and ensure it is sealed properly.

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

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the sensor.
Use a multimeter to measure the resistance and voltage output to verify it meets specifications.
If faulty, remove the old throttle position sensor and install a new one, ensuring it is calibrated properly.

5. Check and Clean MAF Sensor

Locate the MAF sensor in the intake air duct.
Disconnect the electrical connector.
Carefully remove the MAF sensor from its housing.
Clean the sensor with MAF cleaner spray to remove dirt and contaminants.
Reinstall the sensor and reconnect the electrical connector.
