Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the engine is cool and the vehicle is parked on a flat surface.
  • Disconnect the negative battery terminal to avoid electrical shorts.
2. Inspect and Replace Ignition Components

  • Inspect Spark Plugs:

    • Remove spark plug wires or ignition coils.
    • Use a spark plug socket to remove plugs and inspect for wear or damage.

  • Replace Spark Plugs (if needed):

    • Install new spark plugs with the manufacturer’s specified gap.
    • Torque to manufacturer specifications (usually around 15-20 ft-lbs).

  • Inspect and Replace Ignition Coils (if needed):

    • Remove ignition coils, inspect for cracks or carbon tracking.
    • Replace with new coils if damaged.
    • Reinstall coils and ensure they seat properly.
3. Check and Repair Fuel System

  • Test Fuel Pressure:

    • Attach a fuel pressure gauge to the fuel rail.
    • Turn the ignition on (do not start the engine) and check pressure against specifications (typically 50-60 psi).

  • Inspect Fuel Injectors:

    • Remove fuel injectors and check for clogs or leaks.
    • Clean or replace injectors as necessary.

  • Inspect Fuel Pump:

    • If fuel pressure is low, check the fuel pump operation and replace if faulty.
4. Inspect Intake System
  • Check for Vacuum Leaks:
    • Inspect all vacuum hoses for cracks or disconnections.
    • Replace any damaged hoses.
  • Clean Intake and MAF Sensor:
    • Remove the intake hose and clean the MAF sensor using MAF cleaner.
    • Reassemble the intake system ensuring all connections are secure.
5. Reconnect Battery and Clear Codes
  • Reconnect the negative battery terminal.
  • Use the OBD-II scanner to clear any stored error codes.
  • Start the engine to verify repair.
