Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool before starting any work.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new, clean air filter and reassemble the housing cover.
Tools Required: Socket set, new air filter.

3. Test and Replace Fuel Pump (if necessary)

Use a fuel pressure gauge to check the fuel pressure against manufacturer specifications.
If pressure is low, disconnect the fuel lines and electrical connector from the fuel pump.
Remove the fuel pump assembly from the tank following the service manual.
Install the new fuel pump and reconnect all lines and connectors.
Tools Required: Fuel pressure gauge, socket set, screwdrivers.

4. Inspect and Replace Spark Plugs/Ignition Coils (if necessary)

Remove the ignition coils by unscrewing them from the engine.
Take out the spark plugs using a socket wrench and inspect for wear or carbon buildup.
Replace with new spark plugs and reinstall ignition coils.
Tools Required: Socket wrench, torque wrench, new spark plugs, new ignition coils.

5. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner on a clean cloth and wipe the inside of the throttle body to remove carbon buildup.
Reattach the air intake duct securely.
Tools Required: Throttle body cleaner, cloth, socket set.

6. Check and Replace Transmission Fluid (if necessary)

Check the transmission fluid level using the dipstick.
If low or dirty, drain the old fluid and replace it with new transmission fluid as specified by the manufacturer.
Recheck the fluid level after refilling.
Tools Required: Transmission fluid, funnel, socket set.
