Solution

1. Preparation

Gather tools and parts needed for repairs.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Air Filter

Locate the air intake housing.
Remove the screws or clips securing the air intake cover.
Take out the old air filter and inspect it for dirt and damage.
Install a new air filter, ensuring it fits snugly and re-secure the housing.

3. Change Engine Oil

Drain the engine oil by removing the oil drain plug with a socket set.
Replace the oil filter using an oil filter wrench.
Reinstall the drain plug and torque it to the manufacturer’s specifications (check the owner's manual for specific torque values).
Add new engine oil as specified in the owner's manual.

4. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail test port.
Start the engine and check the fuel pressure against manufacturer specifications.
If pressure is low, inspect the fuel pump and fuel filter for issues, replacing them as necessary.

5. Inspect and Replace Spark Plugs

Remove the ignition coil cover to access the spark plugs.
Use a spark plug socket to remove each spark plug.
Inspect for wear or damage; replace with OEM or equivalent spark plugs if necessary.
Reinstall coils and reconnect the wiring.
