Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, multimeter, replacement spark plugs, transmission fluid (if needed), and a vacuum gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Transmission Fluid Issues

Sub-step 1: Remove the transmission dipstick and check fluid level; add fluid if low.
Sub-step 2: If the fluid is dark or burnt, drain the transmission fluid using a socket set and replace it with the specified fluid type (check owner's manual for specifications).
Sub-step 3: Replace the transmission filter if applicable.

3. Replace Spark Plugs and Ignition Coils (if necessary)

Sub-step 1: Disconnect the battery to ensure safety.
Sub-step 2: Remove the engine cover (if present) using a socket set.
Sub-step 3: Disconnect the ignition coil connectors and remove the coils using a socket.
Sub-step 4: Remove the old spark plugs with a spark plug socket; install new spark plugs to the manufacturer's torque specifications (usually around 13-15 lb-ft).
Sub-step 5: Reinstall the ignition coils and reconnect the battery.

4. Inspect and Replace Throttle Position Sensor (if faulty)

Sub-step 1: Disconnect the battery once again.
Sub-step 2: Locate the throttle position sensor on the throttle body.
Sub-step 3: Disconnect the electrical connector and remove the sensor using a socket.
Sub-step 4: Install the new throttle position sensor and reconnect the electrical connector.
