Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery negative terminal for safety.

2. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reassemble the air intake duct securely.

3. Replace Air Filter

Locate the air filter housing and open it.
Remove the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits snugly and seals properly.

4. Test and Replace Fuel Filter (if necessary)

If the fuel pressure gauge indicates low fuel pressure, locate the fuel filter.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect fuel lines from the filter, replace the filter, and reconnect lines securely.

5. Check Transmission Fluid

Locate the transmission dipstick and check the fluid level and condition.
If low, add the manufacturer-recommended transmission fluid until the proper level is reached.
If the fluid is dirty or burnt, consider a transmission fluid change.

6. Reconnect Battery

Reconnect the battery negative terminal securely.
Start the engine and allow it to idle for a few minutes.
