Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical short circuits.
Gather necessary tools and parts.

2. Scan for Error Codes

Use an OBD-II scanner to read and record any diagnostic trouble codes (DTCs).
If codes related to the fuel system, MAF sensor, or ignition system are present, address those specific issues first.

3. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft cloth to clean the throttle body. Ensure the butterfly valve moves freely.
Reinstall the air intake duct securely.

4. Replace Spark Plugs and Ignition Coils (if necessary)

Remove engine cover if applicable using a socket set.
Disconnect the wiring harness from the ignition coils.
Remove spark plugs using a spark plug socket and torque wrench. Check for wear and replace as necessary.
Install new spark plugs and ignition coils, torquing to manufacturer's specification.

5. Fuel System Inspection and Replacement

Check fuel pressure using a fuel pressure gauge; replace the fuel filter if pressure is low.
If the fuel pump is faulty, replace it by removing the fuel pump access panel in the trunk or under the rear seat, disconnecting the fuel lines, and removing the pump assembly.

6. Final Checks

Reconnect the battery.
Start the engine and check for any unusual noises or warning lights.
