Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body.
Ensure the throttle plate moves freely and is not sticking.
Reinstall the air intake duct and reconnect the battery terminal.

3. Replace Fuel Filter (if applicable)

Locate the fuel filter (usually near the fuel tank or along the fuel line).
Relieve fuel system pressure by removing the fuel pump relay while the engine is running until it stalls.
Disconnect the fuel lines from the filter using a fuel line disconnect tool.
Remove the fuel filter and install the new one, ensuring correct orientation (inlet and outlet).
Reconnect the fuel lines and replace the fuel pump relay.

4. Clean or Replace Idle Air Control Valve

Locate the idle air control valve (usually near the throttle body).
Remove the valve using a socket set, taking care not to damage any gaskets.
Clean the valve with throttle body cleaner or replace it if it’s damaged.
Reinstall the valve and ensure all connections are secure.

5. Inspect and Replace Spark Plugs

Remove the ignition coils or spark plug wires to access the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Inspect the old plugs for wear or carbon buildup; replace them if necessary.
Install new spark plugs, ensuring they are gapped correctly as per manufacturer specifications.
Reinstall ignition coils or spark plug wires.
