Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts during repairs.
Ensure the vehicle is on a flat, stable surface and use wheel chocks for safety.

2. Replace Air Filter

Locate the air filter housing.
Remove any screws or clips securing the housing cover.
Take out the old air filter and inspect for dirt and debris.
Install the new air filter, ensuring it is seated properly.
Reattach the housing cover and secure it in place.

3. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth or brush to clean the throttle plate and surrounding area.
Ensure no cleaner residue remains before reassembling the intake duct.

4. Inspect and Replace Spark Plugs

Remove the ignition coil cover if applicable.
Disconnect the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove old spark plugs.
Inspect the old plugs for wear; replace with new plugs at the manufacturer-recommended gap.
Reinstall ignition coils and cover.

5. Check Fuel System

Inspect the fuel pump relay and fuse for faults; replace if necessary.
Disconnect the fuel line at the fuel rail and check for proper pressure using a fuel pressure gauge.
If pressure is low, consider replacing the fuel pump.
