Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Replace Air Filter

Remove the air filter housing cover (typically involves removing screws or clips).
Take out the old air filter and inspect the housing for debris.
Install a new, clean air filter and reassemble the housing.

3. Check and Replace Spark Plugs

Remove the ignition coil(s) by unbolting and unplugging them.
Remove the old spark plugs using a spark plug socket and ratchet.
Check the gap of the new spark plugs and install them according to manufacturer specifications.
Reinstall the ignition coils and reconnect the wiring harness.

4. Inspect and Clean Fuel Injectors

Remove the fuel rail (if applicable) to access the injectors.
Clean the injectors using a specialized fuel injector cleaner.
Reinstall the fuel rail and ensure all connections are secure.

5. Inspect Exhaust System

Visually inspect the exhaust system for any signs of damage or blockages.
If a blockage is found (especially in the catalytic converter), it may need to be replaced.

6. Check Transmission Fluid

Remove the transmission dipstick and check the fluid level and condition.
If the fluid is low or appears burnt, drain and replace with the manufacturer-recommended transmission fluid.
