Solution

1. Preparation

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

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, spark plug gap tool, torque wrench.
Remove the ignition coils by unscrewing the bolts securing them.
Pull out the old spark plugs using a spark plug socket.
Check the gap of the new spark plugs with a gap tool and adjust if necessary.
Install new spark plugs by hand-tightening them and then using the torque wrench to tighten to the manufacturer’s specified torque (typically around 15-20 Nm).
Reinstall the ignition coils and secure them with bolts.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge, basic hand tools.
Locate the fuel rail and connect the fuel pressure gauge to test fuel pressure (should match specifications in the service manual).
If pressure is low, replace the fuel filter and inspect the fuel pump for operation.
Clean or replace fuel injectors if they are clogged.

4. Throttle Body Cleaning

Tools Required: Socket set, throttle body cleaner, clean cloths.
Remove the intake duct connected to the throttle body.
Spray throttle body cleaner onto a cloth and clean the throttle plate and surrounding areas.
Ensure the throttle body opens and closes freely without obstruction.
Reattach the intake duct securely.

5. Transmission Fluid Check

Tools Required: Transmission fluid dipstick (if applicable), funnel.
Check the transmission fluid level using the dipstick while the engine is running and the gear shifter is in 'Park'.
If low, add the appropriate type of transmission fluid as specified by the manufacturer.
