Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during repairs.

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 is seated properly.
Reattach the housing cover and secure it.

3. Check and Replace Fuel Injectors (if necessary)

Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the injectors, using protective gloves and eyewear.
Remove the old injectors using a socket wrench.
Install new fuel injectors, ensuring O-rings are lubricated with engine oil.
Reconnect fuel lines and restore the fuel pump fuse.

4. Inspect and Replace Spark Plugs

Remove the ignition coils by unscrewing them from the engine.
Take out the old spark plugs using a spark plug socket.
Check the gap on new spark plugs and adjust as necessary.
Install new spark plugs and torque them to the manufacturer’s specifications (typically around 13-15 lb-ft).
Reattach ignition coils securely.

5. Tire Pressure and Alignment Check

Use a tire pressure gauge to measure tire pressures and inflate them to the recommended PSI.
If necessary, take the vehicle to a shop for a professional wheel alignment.
