Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Locate the air filter housing.
Remove the screws or clamps securing the housing.
Take out the old air filter and inspect for dirt or damage.
Insert a new air filter (ensure it matches OEM specifications).
Reassemble the air filter housing and secure it.

3. Fuel System Inspection and Repair

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position without starting the engine and check the pressure reading.
If pressure is low, check the fuel pump and replace it if necessary.
Replace the fuel filter if it shows signs of clogging or is due for replacement.

4. Throttle Body Cleaning

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Reassemble the intake duct securely.

5. Ignition System Check

Remove spark plugs and inspect for wear or fouling.
If necessary, replace spark plugs with OEM parts.
Test ignition coils with a multimeter for proper resistance and replace any faulty coils.
