Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery for safety.

2. Check and Replace Spark Plugs

Remove the engine cover if applicable.
Use a socket set to remove the spark plug wire or coil pack.
Use a spark plug socket to carefully remove the spark plugs.
Inspect the spark plugs for wear or fouling; replace if necessary.
Gap the new spark plugs according to manufacturer specifications and install them.
Reattach the coil packs or spark plug wires securely.

3. Clean or Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing.
Take out the existing air filter and inspect for dirt and debris.
If dirty, replace with a new air filter; if reusable, clean it according to the manufacturer's instructions.
Reassemble the air filter housing.

4. Inspect and Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reattach the intake duct securely.

5. Check and Replace Transmission Fluid

Locate the transmission dipstick and check the fluid level; add fluid if low.
If the fluid is discolored or smells burnt, consider a fluid change.
Drain the old fluid using a drain pan, replace with new fluid as specified in the owner's manual.
Recheck the fluid level and ensure it is within the recommended range.
