Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Clean the Throttle Body

Tools Required: Screwdriver set, throttle body cleaner, clean cloth.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner to spray the inside of the throttle body.
Clean the throttle plate and surrounding area with a clean cloth until free of carbon buildup.
Reattach the air intake duct securely.

3. Replace Spark Plugs

Tools Required: Socket set, torque wrench, gap gauge.
Remove the ignition coil cover if applicable.
Disconnect the ignition coil connectors and remove the coils.
Use a socket to remove the spark plugs from the cylinder head.
Install new spark plugs, ensuring the correct gap is set (consult the owner's manual for specifications).
Reinstall ignition coils and connectors.

4. Check and Replace Fuel Filter (if applicable)

Tools Required: Wrenches, fuel line disconnect tool, catch pan.
Locate the fuel filter, usually in line with the fuel lines.
Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using the disconnect tool, and remove the old filter.
Install the new fuel filter making sure the flow direction matches the markings on the filter.
Reconnect the fuel lines and reinstall the fuel pump fuse.

5. Transmission Fluid Inspection and Change

Tools Required: Transmission fluid pump, torque wrench, catch pan.
Check the transmission fluid level using the dipstick; add fluid if low.
If fluid is dirty or burnt, drain the fluid from the transmission pan.
Replace the filter if applicable and refill with the manufacturer-approved transmission fluid according to specifications.
