Solution

1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the air intake system for debris.
Install a new air filter that meets OEM specifications.
Reattach the air filter housing cover and reconnect the battery.

3. Clean or Replace Fuel Injectors

Remove the fuel rail by loosening the mounting bolts with a socket set.
Carefully detach the fuel injectors from the rail.
Clean the injectors using a fuel injector cleaner kit or replace them if necessary.
Reinstall the cleaned or new injectors and reattach the fuel rail, ensuring proper torque specifications are followed.

4. Check and Repair Exhaust System

Inspect the exhaust system from the manifold to the tailpipe for any visible damage or leaks.
If leaks are found, replace or repair the damaged sections using exhaust sealant or clamps.
Ensure that the catalytic converter is functioning properly and replace it if necessary.
