Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Inspect and Replace Air Filter
  • Remove the air filter housing cover using a socket set.
  • Take out the old air filter and inspect for dirt or damage.
  • Install a new air filter, ensuring it fits snugly and seals properly.
  • Reattach the housing cover and tighten it securely.
3. Clean or Replace MAF Sensor
  • Locate the MAF sensor in the air intake duct.
  • Disconnect the electrical connector and remove the sensor using a Torx screwdriver.
  • Clean the sensor with MAF cleaner spray; do not touch the sensor with fingers.
  • If damaged, replace the MAF sensor with a new one.
  • Reinstall the sensor and reconnect the electrical connector.
4. Inspect and Repair Fuel System
  • Visually inspect fuel injectors for leaks.
  • If leaks are found, replace faulty injectors with new ones.
  • Check fuel lines for cracks or wear; replace if necessary.
5. Check Tire Pressure and Alignment
  • Use a tire pressure gauge to check each tire's pressure; inflate to the manufacturer's recommended levels.
  • Inspect wheel alignment; if misaligned, take the vehicle to a professional for adjustment.
