Solution
1. Preparation
  • Gather tools and parts needed for repair.
  • Ensure the vehicle is parked on a flat surface and the ignition is off.
  • Disconnect the battery for safety.
2. Check and Replace Air Filter
  • Locate the air filter housing.
  • Remove the clips or screws securing the housing.
  • Take out the old air filter and inspect it for dirt and debris.
  • Install a new air filter, ensuring it is seated properly.
3. Inspect and Replace Spark Plugs
  • Remove the ignition coil cover if necessary.
  • Disconnect the ignition coils from the spark plugs.
  • Use a socket to remove old spark plugs; inspect for wear or fouling.
  • Install new spark plugs, ensuring to use the correct torque specifications (typically 13 lb-ft for G70).
4. Clean Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
  • Reattach the air intake duct securely.
5. Check Fuel System
  • Use a fuel pressure gauge to connect to the fuel rail.
  • Start the engine and monitor the fuel pressure; compare it to manufacturer specifications (typically around 58-62 psi).
  • If pressure is low, consider replacing the fuel filter or fuel pump.
