Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety.
Allow the engine to cool down if it has been running recently.

2. Inspect and Clean the Throttle Body

Tools Required: Throttle body cleaner, soft brush, socket set
Remove the air intake duct connected to the throttle body.
Unbolt the throttle body using a socket set and gently detach it from the intake manifold.
Clean the throttle plate and body using throttle body cleaner and a soft brush.
Reinstall the throttle body and air intake duct, ensuring all connections are secure.

3. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, socket set, funnel
Locate the transmission dipstick and check fluid level; add fluid if low.
If the fluid is dark or smells burnt, drain the old fluid completely.
Replace with manufacturer-recommended transmission fluid using a fluid pump.
Check for leaks after refilling and ensure fluid is at the correct level.

4. Inspect and Replace Fuel Filter

Tools Required: Fuel line disconnect tool, socket set
Locate the fuel filter and relieve the fuel system pressure.
Use a fuel line disconnect tool to detach the fuel lines from the filter.
Remove the old fuel filter and install a new one, ensuring proper orientation.
Reconnect the fuel lines and check for leaks.

5. Check and Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench
Remove the ignition coils by unbolting them and gently pulling them out.
Use a spark plug socket to remove the spark plugs.
Inspect the old spark plugs for wear; replace them if they are worn or fouled.
Install new spark plugs, ensuring they are torqued to the manufacturer's specifications.
