Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, fuel pressure gauge, multimeter, cleaning supplies.
Disconnect the negative battery terminal to ensure safety while working on the vehicle.

2. Addressing Error Codes

If diagnostic codes were found, refer to the specific code for guidance on repair steps.
Clear the codes from the system and perform a test drive to see if they reappear.

3. Replace Air Filter (if necessary)

Remove the air filter cover by unscrewing or unclipping it.
Take out the old air filter and inspect the housing for dirt or debris.
Install the new air filter, ensuring it fits securely, and reattach the cover.

4. Fuel System Inspection

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "on" position (without starting the engine) to check for initial pressure.
If pressure is below specifications (refer to service manual), replace the fuel pump or filter as necessary.

5. Throttle Body Cleaning

Remove the throttle body from the intake manifold by loosening the bolts.
Use throttle body cleaner and a clean cloth to remove carbon buildup from the throttle plate and housing.
Reinstall the throttle body and torque bolts to manufacturer's specifications.

6. Ignition System Check

Inspect spark plugs for wear and replace if necessary. Ensure gaps are set to specifications.
Test ignition coils using a multimeter; replace any coils that do not meet resistance specifications.
