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. Inspect and Replace Air Filter

Remove the air filter housing cover.
Take out the old air filter and inspect it for dirt and clogging.
Install a new air filter, ensuring it fits securely.
Reattach the air filter housing cover.

3. Fuel Injector Cleaning/Replacement

If clogged, use a fuel injector cleaning kit according to the manufacturer's instructions.
If the injectors are leaking or severely clogged, remove the fuel rail and replace the injectors.
Reinstall the fuel rail and ensure all connections are secure.

4. Address Vacuum Leaks

Inspect all vacuum hoses for cracks or damage.
Replace any damaged hoses.
Use a smoke machine or carburetor cleaner to find leaks around the intake manifold.

5. Reset Engine Control Unit (ECU)

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes.
Perform a drive cycle to allow the ECU to recalibrate.
