Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Spark Plugs

Remove the ignition coil cover (if applicable) for access.
Disconnect the ignition coils by unplugging the electrical connectors.
Unbolt the ignition coils from the engine and carefully remove them.
Use a spark plug socket to remove the old spark plugs.
Install new spark plugs, ensuring the correct gap settings (typically 0.043 inches for most models).
Reinstall the ignition coils and reconnect the electrical connectors.
Reattach the coil cover.

3. Fuel System Cleaning

Add a fuel system cleaner to the gas tank according to the product instructions.
Run the vehicle for a short distance to allow the cleaner to circulate through the system.

4. Transmission Fluid Change

Raise the vehicle and secure it on jack stands.
Remove the transmission pan bolts and lower the pan to drain old fluid.
Replace the transmission filter if applicable.
Clean the pan and reinstall it with a new gasket.
Refill the transmission with the manufacturer-recommended fluid type and quantity (typically around 4-8 quarts).

5. Inspect and Replace Air Filter

Locate the air filter housing and unclip or unbolt the cover.
Remove the old air filter and clean the housing as needed.
Install a new air filter ensuring it fits snugly.
