Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a clean cloth to remove carbon deposits from the throttle plate.
Reinstall the air intake duct securely and reconnect the battery.

3. Fuel System Inspection

Locate the fuel pressure test port on the fuel rail.
Connect a fuel pressure gauge and turn the ignition to the "ON" position without starting the engine. Check the pressure reading against the manufacturer's specifications.
If low, inspect the fuel filter and fuel pump for blockages or failures.

4. Ignition System Check

Remove the spark plugs using a socket wrench.
Inspect the spark plugs for wear, carbon buildup, or damage.
Replace any faulty spark plugs with ones that meet OEM specifications.
Reinstall the spark plugs and ensure they are torqued to the manufacturer’s specifications.

5. Transmission Fluid Check

Locate the transmission dipstick and remove it.
Check the fluid level and condition; it should be pink and clear, not dark or burnt.
If low, add the appropriate transmission fluid type as specified in the owner's manual.
