Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Spark Plugs

Remove the engine cover if necessary.
Using a socket set, remove the ignition coils from the spark plugs.
Extract spark plugs using a spark plug socket; inspect for wear or fouling.
Replace old spark plugs with new ones, ensuring they are gapped according to manufacturer specifications (typically around 0.028-0.032 inches).
Reinstall ignition coils and engine cover.

3. Clean or Replace Air Filter

Open the air filter housing, typically secured with clips or screws.
Remove the old air filter and inspect it for dirt and damage.
Clean the air filter housing with a damp cloth to remove debris.
Install a new air filter, ensuring it fits snugly in the housing.
Close the air filter housing securely.

4. Inspect and Replace Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the sensor.
Remove the sensor using a socket set and inspect for damage.
Install the new throttle position sensor, following manufacturer alignment.
Reconnect the electrical connector.

5. Check Transmission Fluid

Locate the transmission dipstick or fill plug.
Remove the dipstick or plug and wipe it clean.
Insert it back to check fluid level; add the appropriate type of transmission fluid if low (refer to owner’s manual for specifications).
Inspect fluid condition; if it appears dark or contaminated, consider a fluid change.
