Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Replace Air Filter

Remove the air filter housing cover using a screwdriver or socket set.
Replace the old air filter with a new one.
Reassemble the air filter housing and secure it properly.

3. Fuel System Check

Connect the fuel pressure gauge to the fuel rail service port.
Start the engine and monitor the fuel pressure; it should be within the manufacturer’s specified range (typically around 30-50 psi).
If pressure is low, inspect the fuel pump and fuel filter for issues. Replace the fuel filter if clogged.

4. Inspect and Replace Spark Plugs

Remove the ignition coils by unscrewing them and disconnecting the electrical connectors.
Take out the spark plugs with a spark plug socket; check for wear and replace if necessary (gap to manufacturer specifications).
Reinstall the new spark plugs and ignition coils.

5. Clean Throttle Body

Remove the throttle body from the intake manifold by unscrewing the mounting bolts.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Reinstall the throttle body and ensure all connections are secure.
