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 ensure safety.

2. Replace Air Filter

Remove the air filter housing cover using a screwdriver.
Take out the old air filter and inspect for dirt and debris.
Install a new air filter, ensuring it fits snugly.
Reattach the housing cover and tighten screws.

3. Clean or Replace Fuel Injectors

If cleaning, use a fuel injector cleaning kit: connect the kit to the fuel rail and follow instructions to clean.
If replacing, relieve fuel system pressure, disconnect fuel lines, and remove the old injectors using a socket set.
Install new injectors, applying a small amount of engine oil to the O-rings for a better seal.
Reconnect fuel lines and test for leaks.

4. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set and inspect the spark plugs.
Replace with new spark plugs if worn (check gap specifications).
Reinstall ignition coils, ensuring they are seated correctly.

5. Check for Vacuum Leaks

Inspect all hoses connected to the intake manifold for cracks or disconnections.
If any leaks are found, replace the damaged hoses, ensuring all connections are secure.
