Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.

2. Address Engine Performance Issues

Air Filter Replacement:
- Locate the air filter housing.
- Remove the screws or clips securing the housing cover.
- Replace the old air filter with a new one (OEM recommended).
Throttle Body Cleaning:
- Disconnect the negative battery terminal.
- Remove the throttle body from the intake manifold (use appropriate socket set).
- Clean the throttle body using throttle body cleaner and a soft brush.
- Reassemble and reconnect the throttle body.

3. Fuel System Inspection

Check Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the ON position (do not start) and check the pressure.
- If pressure is below specification, consider replacing the fuel pump or filter.

4. Transmission Fluid Check

Inspect Transmission Fluid:
- Locate the transmission dipstick.
- Remove the dipstick, clean it, and reinsert to check fluid level.
- If the fluid is burnt or contaminated, perform a transmission fluid change.

5. Final Assembly

Reconnect any components removed during the process.
Reconnect the negative battery terminal.
Start the engine and let it idle for a few minutes to ensure everything is functioning properly.
