Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal for safety.

2. Address Fault Codes

Using an OBD-II scanner, retrieve and document the fault codes.
Research each code to understand potential issues and needed repairs.

3. Inspect and Replace Spark Plugs

Remove the engine cover if applicable.
Disconnect the ignition coils and remove them from the spark plugs.
Remove the old spark plugs using a socket wrench.
Inspect for wear; replace with new spark plugs as necessary, ensuring the proper torque (typically 13-15 ft-lbs).

4. Check and Replace Ignition Coils

If misfires are evident, test ignition coils with a multimeter or replace them if damaged.
Reinstall new coils and connect them securely.

5. Inspect Fuel System

Check fuel injectors for clogs or leaks. Clean or replace as necessary.
Test fuel pressure using a fuel pressure gauge to ensure it meets manufacturer specifications.

6. Check MAF Sensor and Throttle Body

Disconnect the MAF sensor and clean it with MAF sensor cleaner.
Inspect the throttle body for carbon buildup; clean if necessary.

7. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and observe for any warning lights or issues.
