Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing.
Take out the old air filter and inspect for dirt and debris.
Insert a new air filter, ensuring it fits snugly.
Reattach the housing cover and secure it.

3. Clean or Replace Fuel Injectors

Remove the fuel rail by unscrewing the retaining bolts.
Disconnect the electrical connectors and fuel lines; use a rag to catch any fuel spillage.
If cleaning, soak the injectors in a cleaning solution and use a cleaning kit to flush them.
If replacing, install new injectors, ensuring they seat properly in the fuel rail.
Reconnect fuel lines and electrical connectors.

4. Replace Spark Plugs

Remove the ignition coil or wires attached to the spark plugs.
Using a spark plug socket, unscrew the old spark plugs.
Inspect the condition of the spark plugs; replace if fouled or worn.
Install new spark plugs, hand-tightening them first, then torque to manufacturer specifications.

5. Repair Vacuum Leaks

Inspect all vacuum hoses and gaskets for cracks or disconnections.
Replace faulty hoses and reseal any leaking gaskets with appropriate sealant.
Test the repaired hoses and gaskets with a smoke machine to confirm no leaks remain.
