Solution

1. Preparation

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

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt or damage.
Replace with a new, clean air filter.
Reassemble the air filter housing and reconnect any clips or screws.

3. Check and Adjust Fuel Pressure

Attach the fuel pressure gauge to the fuel rail test port.
Start the engine and observe the fuel pressure reading; it should meet manufacturer specifications (consult service manual).
If pressure is low, inspect fuel pump and fuel filter; replace if necessary.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and body.
Reattach the intake duct securely.

5. Inspect Ignition System

Remove the spark plugs using a spark plug socket.
Check for wear or fouling; replace with new spark plugs if necessary.
Inspect ignition coils for cracks or damage and replace them if needed.

6. Check Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe clean, reinsert, and remove again to check fluid level.
If fluid is low, top off with the manufacturer-recommended transmission fluid.
If fluid appears burnt or dirty, consider flushing the transmission.
