Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts during inspection.

2. Inspect and Clean the Throttle Body

Remove the air intake duct by loosening the hose clamps and disconnecting any sensors.
Use throttle body cleaner and a soft cloth to clean the throttle plate and housing. Ensure no debris falls into the intake.
Reassemble the air intake duct and reconnect all sensors.

3. Check and Replace Fuel Filter

Locate the fuel filter (refer to the vehicle manual for the exact location).
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using a line wrench.
Replace the old filter with a new one, ensuring the flow direction is correct.
Reconnect the fuel lines and replace the fuel pump fuse.

4. Inspect and Replace Spark Plugs (if necessary)

Remove the engine cover (if applicable) by unscrewing any fasteners.
Disconnect the ignition coils and remove them from the spark plugs.
Remove spark plugs using a spark plug socket and inspect them for wear or damage.
Replace with new spark plugs, ensuring to torque them to manufacturer specifications (usually around 13-15 lb-ft).
Reassemble the ignition coils and engine cover.

5. Transmission Fluid Check and Replacement

Locate the transmission dipstick and check fluid level and condition.
If low or burnt, drain the fluid using a fluid pump or by removing the transmission pan.
Replace with the manufacturer-recommended transmission fluid, filling to the correct level as per the dipstick.
