Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during repairs.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and clean the housing.
Install the new air filter, ensuring it is seated correctly.
Reattach the air filter housing cover and secure it.

3. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires carefully.
Use a socket wrench to remove the old spark plugs.
Check the gap on the new spark plugs and adjust if necessary.
Install the new spark plugs with a torque of 13 lb-ft.
Reconnect the ignition coils or spark plug wires.

4. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
Wipe away any carbon deposits with a clean cloth.
Reinstall the air intake duct and ensure all connections are secure.

5. Check Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition key to the "On" position to check for the proper fuel pressure (refer to vehicle specifications).
If pressure is low, inspect the fuel pump and fuel filter for issues.
