Solution
1. Preparation
  • Gather tools and parts needed.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Replace Air Filter
  • Remove the air filter housing cover using a socket set.
  • Carefully remove the old air filter.
  • Inspect the air filter housing for debris and clean if necessary.
  • Install a new air filter, ensuring it is properly seated, and reattach the housing cover.
3. Inspect and Clean Throttle Body
  • Remove the throttle body from the intake manifold using a socket set.
  • Use throttle body cleaner and a soft brush to clean the throttle plate and the inside of the throttle body.
  • Reinstall the throttle body, ensuring all gaskets are in good condition to prevent vacuum leaks.
4. Check Fuel System
  • Inspect fuel lines and connections for any signs of leakage; replace any damaged components.
  • Test fuel pressure using a fuel pressure gauge; if not within specifications, consider replacing the fuel pump or filter.
  • Clean or replace fuel injectors if clogged.
5. Reconnect Battery and Clear Codes
  • Reconnect the battery terminals.
  • Use the OBD-II scanner to clear any error codes that were previously logged.
