Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative terminal of the battery to avoid electrical issues.
Gather all necessary tools and parts.

2. Inspect and Clean Air Intake

Remove the air intake duct using a socket set.
Inspect the air filter for dirt and blockages; replace if necessary.
Clean the throttle body using throttle body cleaner and a soft brush.
Reattach the air intake duct securely.

3. Fuel System Check

Connect a fuel pressure gauge to the fuel rail.
Start the engine and monitor fuel pressure; it should match specifications (check service manual).
If pressure is low, inspect and replace the fuel filter or fuel pump as needed.

4. Ignition System Inspection

Remove the ignition coil cover.
Inspect and replace spark plugs if worn (check gap and condition).
Test ignition coils with a multimeter to ensure they are functioning within specifications.
Replace any faulty ignition coils.

5. Verify and Replace Transmission Fluid (if necessary)

Locate the transmission dipstick and check fluid level and condition.
If fluid is low or burnt, drain and replace with the manufacturer's recommended transmission fluid.
Recheck fluid levels and ensure the transmission operates smoothly.
