Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Disconnect the battery to prevent any electrical issues during repairs.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a screwdriver.
Inspect the air filter; if dirty, replace it with a new OEM filter.
Reassemble the air filter housing cover securely.

3. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and bore.
Reassemble the intake duct and ensure all clamps are tightened.

4. Replace Spark Plugs and Ignition Coils (if needed)

Remove the ignition coil connector and bolt using a socket wrench.
Pull out the ignition coil and replace it if damaged.
Use a spark plug socket to remove old spark plugs and install new ones, torquing to manufacturer specifications (typically around 13 lb-ft).
Reconnect the ignition coils.

5. Check and Replace Transmission Fluid (if contaminated)

Remove the transmission fluid dipstick and check fluid level and condition.
If fluid is dark or has a burnt smell, drain the transmission fluid by removing the pan.
Replace with new OEM transmission fluid and ensure the pan is reinstalled with a new gasket.
