Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Replace Spark Plugs

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove the ignition coil covers if applicable.
3. Unscrew the spark plugs using a spark plug socket and ratchet.
4. Inspect the old spark plugs for wear or fouling.
5. Install new spark plugs, ensuring the gap is set to manufacturer specifications (0.044 inches).
6. Torque the spark plugs to the manufacturer's specified torque (typically around 13 lb-ft).

3. Inspect/Replace Ignition Coils

Sub-steps:
1. Remove the ignition coils by unscrewing the mounting bolts.
2. Check for cracks or damage in the coils.
3. If faulty, replace with new ignition coils and reattach the connectors securely.

4. Clean or Replace Fuel Injectors

Sub-steps:
1. Disconnect the fuel lines (use caution as fuel may spray).
2. Remove the fuel rail and fuel injectors.
3. Clean the injectors using a proper cleaner or replace them if necessary.
4. Reinstall the fuel injectors and ensure all seals are intact.

5. Check for Air Intake Leaks

Sub-steps:
1. Inspect all air intake hoses and clamps for cracks or loose connections.
2. Replace any damaged components.
3. Reconnect all hoses securely.
