Solution

1. Preparation

Gather tools and parts.
Disconnect the battery before starting any electrical work.
Safety glasses and gloves should be worn during the repair.

2. Clean Throttle Body

Remove the air intake duct from the throttle body.
Use throttle body cleaner and a soft cloth to clean any carbon deposits on the throttle plate.
Reattach the air intake duct securely.

3. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable).
Unscrew and remove the old spark plugs using a spark plug socket.
Check the gap on the new spark plugs and adjust as necessary.
Install the new spark plugs, tightening to the manufacturer’s specified torque (usually around 13-15 lb-ft).
Reattach the ignition coil cover.

4. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it to check the fluid level.
If fluid is low or discolored, drain the old fluid using a fluid pump or by removing the drain plug.
Replace with new transmission fluid as specified by the manufacturer (consult the owner's manual for fluid type).
Recheck the fluid level after running the engine for a few minutes.

5. Inspect Vacuum Hoses

Visually inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses with new ones, ensuring tight connections.
