Solution

1. Preparation

Gather necessary tools and safety equipment.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during electrical work.

2. Air Filter Replacement

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt or debris.
Install a new air filter, ensuring it fits snugly in place.
Reattach the air filter housing cover and tighten screws to the manufacturer's torque specifications.

3. Throttle Position Sensor (TPS) Replacement

Locate the throttle body on the engine.
Disconnect the TPS connector and remove the mounting screws using a screwdriver.
Install the new TPS, ensuring proper alignment.
Reconnect the TPS connector and clear any stored error codes using the OBD-II scanner.

4. Spark Plug and Ignition Coil Inspection

Remove the ignition coil cover if applicable.
Use a socket set to remove each ignition coil and inspect for cracks or wear.
Replace any faulty ignition coils and install new spark plugs, ensuring proper gap size.
Reattach the ignition coil cover.

5. Transmission Fluid Check and Replacement

Check the transmission fluid level using the dipstick while the engine is running.
If low, add the manufacturer-recommended transmission fluid.
If the fluid is contaminated, drain and replace it by removing the transmission pan and replacing the fluid and filter.

6. Fuel System Inspection

Inspect the fuel filter for clogs; replace if necessary.
Test the fuel pump's operation using a fuel pressure gauge to ensure it meets specifications.
Replace the fuel pump if it fails to operate correctly.
