Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Inspect and Replace Fuel Filter

Locate the fuel filter, which is typically near the fuel tank or along the fuel line.
Use a wrench to disconnect the fuel lines from the filter; have a container ready to catch any spilled fuel.
Remove the old fuel filter and install the new one, ensuring the flow direction matches the original filter.
Reconnect the fuel lines securely and check for any leaks.

3. Clean or Replace Fuel Injectors

Remove the engine cover if necessary to access the fuel injectors.
Disconnect the electrical connectors and fuel lines from the injectors.
Use an injector cleaner or replace the injectors if they are clogged or malfunctioning.
Reassemble all components, ensuring connections are tight and secure.

4. Check and Replace Air Filter

Locate the air filter housing and remove the cover.
Take out the old air filter and inspect it for dirt or blockages.
Replace with a new air filter if it appears clogged or dirty.
Reassemble the air filter housing securely.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and observe for any signs of rough idling or stalling.
