Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt and debris.
Insert a new air filter (if needed) and reassemble the housing cover.

3. Clean Throttle Body

Remove the intake duct connected to the throttle body using a screwdriver.
Spray throttle body cleaner into the throttle body and use a soft brush to remove carbon deposits.
Wipe clean with a lint-free cloth and reattach the intake duct securely.

4. Test and Replace Fuel Filter (if applicable)

Locate the fuel filter and relieve fuel pressure from the system.
Disconnect the fuel lines using a fuel line disconnect tool.
Replace with a new fuel filter and ensure all connections are tight.

5. Inspect and Replace Ignition Components

Remove spark plug wires or ignition coil connectors.
Use a spark plug socket to remove the spark plugs and inspect for wear.
Replace with new spark plugs as per manufacturer specifications.
Reconnect ignition components securely.
