Solution
1. Preparation
  • Gather tools and parts needed.
  • Disconnect the battery to ensure safety.
  • Allow the engine to cool before starting work.
2. Inspect and Replace Spark Plug
  • Tools Required: Socket set, torque wrench
  • Remove the spark plug using a socket wrench.
  • Inspect the spark plug for deposits, wear, or damage. Replace it if necessary.
  • Torque the new spark plug to the manufacturer's specifications (typically 13-15 lb-ft).
3. Inspect and Replace Ignition Coil
  • Tools Required: Socket set, multimeter
  • Disconnect the electrical connector from the ignition coil.
  • Remove the ignition coil from cylinder 1 using a socket wrench.
  • Test the ignition coil using a multimeter to ensure it is functioning properly. Replace if faulty.
  • Install the new ignition coil and reconnect the electrical connector.
4. Check Fuel Injector
  • Tools Required: Noid light or multimeter
  • Disconnect the fuel injector connector for cylinder 1.
  • Use a noid light to check for injector pulse. If no pulse is detected, further diagnose the wiring or ECM.
  • If the injector is faulty, remove it and replace it with a new one. Reconnect the electrical connector.
5. Perform a Compression Test
  • Tools Required: Compression tester
  • Remove the spark plug for cylinder 1.
  • Insert the compression tester and crank the engine.
  • Compare the compression reading to the manufacturer’s specifications. If low, further investigation into valve or piston issues may be needed.
