Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shocks or accidental startups.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Use throttle body cleaner to spray inside the throttle body while opening the throttle plate manually.
Wipe clean with a lint-free cloth, ensuring no debris is left behind.
Reattach the air intake duct and secure it properly.

3. Inspect and Replace Fuel Filter (if needed)

Locate the fuel filter (refer to the service manual for exact location).
Release the fuel pressure using a pressure gauge or by loosening the fuel cap.
Disconnect the fuel lines carefully to avoid spills.
Remove the fuel filter and replace it with a new one, ensuring correct orientation.
Reconnect the fuel lines and check for leaks.

4. Check and Replace Transmission Fluid (if needed)

Locate the transmission fluid dipstick or fill port.
Check the fluid level and condition. If the fluid is dark or has a burnt smell, it needs to be replaced.
Drain the old transmission fluid using a fluid pump.
Refill with the manufacturer-recommended transmission fluid type, typically using a funnel.
Check the fluid level again and top off as necessary.
