Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety while working on electrical components.
  • Allow the engine to cool before starting work.
2. Replace Air Filter
  • Locate the air filter housing.
  • Remove the screws or clips securing the housing.
  • Replace the old air filter with a new one, ensuring it fits snugly.
  • Reassemble the air filter housing and secure it.
3. Clean or Replace Fuel Injectors
  • If injectors are clogged, use a fuel injector cleaning kit to clean them.
  • Alternatively, remove the fuel injectors using a socket set and replace them with new ones, ensuring correct orientation and seating.
  • Reinstall the fuel rail and reconnect any electrical connectors.
4. Inspect and Repair Exhaust System
  • Visually inspect the exhaust system for any cracks, holes, or loose connections.
  • Use exhaust patch kits or replace damaged sections as needed.
  • Ensure all clamps and bolts are properly tightened.
5. Check Tire Pressure and Condition
