Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, cleaning supplies, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before working on electrical components.

2. Clean Air Intake System

Remove the air intake ducting.
Inspect the air filter; replace if dirty or clogged.
Clean the throttle body using throttle body cleaner and a soft cloth.
Reassemble the air intake system ensuring all connections are secure.

3. Fuel System Inspection

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position without starting the engine to check fuel pressure.
If pressure is below specifications (refer to service manual for exact values), replace the fuel pump and filter.
If pressure is adequate, proceed to check fuel injectors for clogs using a fuel injector cleaner.

4. Spark Plug Replacement

Remove the ignition coils and spark plugs using a socket set.
Inspect the spark plugs for wear or fouling; replace with OEM specifications if necessary.
Reinstall ignition coils ensuring proper torque specs are followed.

5. Transmission Fluid Check

Locate the transmission dipstick and remove it to check fluid level.
If low or dirty, drain the transmission fluid and replace with the manufacturer-recommended fluid.
Refill to the appropriate level and check for leaks.
