2. Inspect and Replace Spark Plugs

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the ignition coil(s) by unbolting and disconnecting the harness.
• Use the spark plug socket to remove the old spark plugs.
• Inspect the old spark plugs for signs of wear or fouling.
• Install new spark plugs, tightening to the manufacturer’s specified torque (usually around 13-15 lb-ft).
• Reinstall the ignition coils, ensuring they are securely connected.

3. Test and Replace Ignition Coils

• Tools Required: Multimeter, socket set.
• Using a multimeter, check the resistance of each ignition coil; compare readings with manufacturer specifications.
• Remove any faulty ignition coils and replace them with new ones.
• Reconnect all electrical connectors and harnesses.

4. Clean or Replace Fuel Injectors

• Tools Required: Fuel injector cleaning kit or replacement injectors, socket set.

• Reconnect fuel lines and electrical connectors securely.

5. Check for Vacuum Leaks

• Tools Required: Smoke machine or carburetor cleaner.
