Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery before starting any electrical work.
2. Replace Air Filter
  • Remove the air filter cover using a socket set.
  • Take out the old air filter and inspect the housing for debris.
  • Install a new, clean air filter and reattach the cover.
  • Tools Required: Socket set, clean cloth for debris.
3. Fuel System Inspection
  • Use a fuel pressure gauge to check the fuel pump output.
  • If pressure is low, replace the fuel pump.
  • Inspect fuel injectors for clogs; clean or replace as needed.
  • Tools Required: Fuel pressure gauge, injector cleaning kit or new injectors.
4. Spark Plug Replacement
  • Remove the ignition coil covers using a socket set.
  • Take out the old spark plugs using a spark plug socket.
  • Install new spark plugs and torque them to manufacturer specifications (usually around 13-16 ft-lbs).
  • Reassemble the ignition coils and covers.
  • Tools Required: Spark plug socket, torque wrench.
5. Tire Pressure Check
  • Use a tire pressure gauge to check each tire's pressure.
  • Inflate or deflate tires to match the manufacturer’s recommended PSI.
  • Inspect tires for uneven wear or damage and replace if necessary.
  • Tools Required: Tire pressure gauge, air compressor.
