Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical shock.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Unbolt the throttle body from the intake manifold using a socket set.
Clean the throttle body using throttle body cleaner and a soft brush.
Reinstall the throttle body with a new gasket, ensuring proper torque (typically around 10-15 Nm).
Reconnect the air intake duct.

3. Check Fuel System

Locate the fuel rail and connect a fuel pressure gauge.
Start the engine and check the fuel pressure; it should match manufacturer specifications (usually around 50-60 psi).
If pressure is low, replace the fuel pump or filter as necessary.
Reconnect all components securely after testing.

4. Transmission Fluid Check

Locate the transmission dipstick and remove it to check fluid levels.
If fluid is low, add the appropriate transmission fluid as specified in the owner's manual.
If the fluid appears burnt or dirty, replace the transmission fluid and filter. Follow manufacturer guidelines for draining and refilling.
