Symptoms
  • Check Engine Light: Illuminated due to misfire codes.
  • Rough Idle: Engine runs unevenly at idle.
  • Loss of Power: Acceleration may feel sluggish.
  • Poor Fuel Economy: Increased fuel consumption.
  • Stalling: Engine may unexpectedly shut off.
Diagnostic Steps

  1. Scan for Error Codes:

    • Use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) related to misfires or ignition issues.

  2. Visual Inspection:

    • Open the hood and visually inspect the ignition coil and wiring harness connected to the spark plugs for any signs of damage or wear.

  3. Check Spark Plug Condition:

    • Remove the ignition coils or spark plug wires carefully.
    • Inspect the spark plugs for any signs of wear, such as corrosion, carbon deposits, or oil fouling.
Tools Required
  • OBD-II Scanner
  • Socket set (10mm socket and ratchet)
  • Torque wrench
  • Spark plug socket (usually 5/8” or 13/16”)
  • Extension for the socket wrench
  • Dielectric grease (optional)
Repair Instructions

  1. Preparation:

    • Park the vehicle on a level surface and engage the parking brake.
    • Disconnect the negative battery terminal to prevent electrical shorts.

  2. Remove Ignition Coils:

    • Locate the ignition coils (usually on top of the engine).
    • Unplug the electrical connector from each coil.
    • Remove the bolts securing the coils using a socket wrench and carefully pull the coils out.

  3. Remove Spark Plugs:

    • Using the spark plug socket and an extension, carefully unscrew each spark plug from the cylinder head.
    • Be cautious of any debris falling into the cylinder when removing the spark plugs.

  4. Inspect Spark Plugs:

    • Check each spark plug for:
      • Normal wear (electrode wear, gap).
      • Carbon fouling (black deposits).
      • Oil fouling (wet appearance).
      • Cracks or damage.
    • If any spark plug shows excessive wear or damage, replace it.

  5. Install New Spark Plugs:

    • Set the gap of the new spark plugs according to the manufacturer’s specifications (usually around 0.044 inches for the MDX).
    • Apply a small amount of anti-seize compound to the threads (optional).
    • Carefully thread the spark plugs into the cylinder head and tighten them to the manufacturer's torque specification (usually around 13.5 lb-ft for aluminum heads).

  6. Reinstall Ignition Coils:

    • Apply dielectric grease to the inside of the ignition coil boots (optional).
    • Reinstall the ignition coils and secure them with bolts.
    • Reconnect the electrical connectors.

  7. Reconnect Battery:

    • Reconnect the negative battery terminal.
Estimated Time for Repair
  • Approximately 1 to 2 hours, depending on experience and accessibility of spark plugs.
Safety Warnings
  • Always disconnect the battery before working on the ignition system.
  • Allow the engine to cool before beginning any work to avoid burns.
  • Use appropriate tools to avoid damaging the spark plugs or ignition system components.
