Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported if necessary.
Disconnect the battery to prevent electrical shorts during repairs.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits snugly.
Reassemble the air filter housing cover and tighten screws to factory specifications.

3. Clean or Replace Fuel Injectors

If using injector cleaner, add it to the fuel tank per the manufacturer's instructions.
For removal, disconnect the battery and relieve fuel system pressure.
Disconnect fuel injector electrical connectors and remove the fuel rail bolts.
Carefully remove the fuel injectors from the rail and inspect for debris.
Clean the injectors with a specialized cleaner or replace them with new ones if necessary.

4. Replace Spark Plugs

Remove the ignition coil or spark plug wires (whichever applies) to access the spark plugs.
Use a spark plug socket and ratchet to remove old spark plugs.
Check the gap on new spark plugs and install them, tightening to manufacturer's torque specifications.
Reconnect ignition coils or spark plug wires.

5. Inspect Exhaust System

Visually inspect the exhaust system for any cracks or loose connections.
Use a soapy water solution to check for leaks at joints and connections.
Replace any damaged components as needed, ensuring all bolts are torqued to specifications.
