Solution

1. Preparation

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

2. Inspect and Replace Air Filter

Locate the air filter housing.
Open the housing and remove the old air filter.
Inspect the air filter for dirt and debris; replace if necessary.
Install a new air filter, ensuring it is seated properly.

3. Check and Repair Vacuum Leaks

Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
Replace any damaged hoses with new ones.
Use a smoke test if necessary to identify hard-to-find leaks.

4. Clean or Replace Fuel Injectors

If fuel injectors are clogged, use a fuel injector cleaning kit to clean them.
If cleaning does not resolve the issue, remove the injectors and replace them with new ones.
Ensure proper sealing and connection upon reinstallation.

5. Replace or Repair Sensors

Check the Mass Air Flow (MAF) sensor for dirt; clean it with MAF cleaner if necessary.
Test the Oxygen (O2) sensors for proper function; replace any that are faulty.
Reconnect any disconnected electrical connectors.
