Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Clean the Throttle Body

Remove the air intake duct from the throttle body.
Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
Use a clean cloth to wipe away any carbon deposits.
Reinstall the air intake duct securely.

3. Check and Replace Fuel Filter

Locate the fuel filter (check service manual for specific location).
Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the filter using the appropriate tools.
Replace the old fuel filter with a new one, ensuring correct orientation.
Reconnect the fuel lines and reinstall the fuel pump relay.

4. Inspect Transmission Fluid

Locate the transmission dipstick (if applicable) and remove it.
Check the fluid level and condition (should be bright red and should not smell burnt).
If low, add the recommended type of transmission fluid.
If fluid is dark or burnt, consider a transmission fluid change.
