1. Preparation

Gather tools and parts necessary for the repair.
Disconnect the negative terminal of the battery to ensure safety.

Tools Required:

OBD-II scanner
Fuel pressure gauge
Socket set
Torque wrench
Cleaning supplies (carbon cleaner, rags)

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 it to the manufacturer's specifications.

3. Clean Throttle Body

Locate the throttle body and remove the intake duct.
Use throttle body cleaner to spray the interior of the throttle body.
Gently wipe the throttle plate and surrounding areas with a clean rag.
Reattach the intake duct and ensure all clamps are secure.

4. Replace Spark Plugs

Remove the ignition coil connectors and unscrew the coil packs.
Use a socket to remove the old spark plugs.
Install new spark plugs, ensuring they are gapped according to manufacturer specifications.
Reinstall the coil packs and connect the ignition coil connectors.

5. Check Fuel System

Connect the fuel pressure gauge to the fuel rail.
Start the engine and observe the fuel pressure reading, ensuring it meets the specifications.
If pressure is low, inspect the fuel pump and fuel filter for issues.
