Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Air Intake System

Remove the air filter and inspect for dirt or damage. Replace if necessary.
Clean the air intake ducts and throttle body using an appropriate cleaner.
Reinstall the air filter and ensure all connections are secure.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (do not start the engine) and check the pressure reading.
If the pressure is below specifications, replace the fuel pump or inspect the fuel filter for clogs.

4. Check Spark Plug and Ignition System

Remove spark plugs and inspect for wear or fouling.
Replace any worn or damaged spark plugs with OEM parts.
Test ignition coils for resistance using a multimeter and replace if necessary.

5. Transmission Fluid Inspection

Locate the transmission dipstick and check the fluid level.
If low, add the manufacturer-recommended transmission fluid.
Inspect for any signs of leaks in the transmission system.
