Solution
1. Preparation
  • Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, vacuum gauge.
  • Disconnect the negative terminal of the battery to prevent electrical shorts.
2. Replace Air Filter
  • Remove the air filter housing cover using a socket set.
  • Take out the old air filter and inspect the housing for debris.
  • Install a new air filter, ensuring it fits snugly in the housing.
  • Reattach the air filter housing cover and tighten the fasteners.
3. Fuel System Inspection
  • Tools Required: Fuel pressure gauge.
  • Disconnect the fuel pump relay to prevent fuel pump operation.
  • Connect the fuel pressure gauge to the fuel rail service port.
  • Reconnect the fuel pump relay and turn the ignition to the ON position (do not start the engine).
  • Check the fuel pressure reading against manufacturer specifications. If low, replace the fuel pump.
4. Inspect and Replace Ignition Components
  • Remove spark plug wires and inspect for cracks or corrosion.
  • Use a multimeter to test ignition coils for proper resistance.
  • Replace worn or damaged spark plugs and ignition coils as necessary.
5. Throttle Position Sensor (TPS) Check
  • Locate the TPS on the throttle body.
  • Use a multimeter to check for proper voltage output as you manually move the throttle plate.
  • If readings are out of specification, replace the TPS.
6. Vacuum Leak Inspection
  • Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
  • Use a vacuum gauge to test the engine's vacuum at idle. Low readings may indicate a leak.
  • Replace any damaged hoses and recheck vacuum levels.
