Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shock.

2. Replace Air Filter

Tools Required: Socket set, screwdrivers
Remove the air intake cover using the appropriate tools.
Take out the old air filter and inspect the housing for debris.
Install the new air filter, ensuring a snug fit.
Reattach the air intake cover securely.

3. Check and Replace Fuel Pump (if necessary)

Tools Required: Fuel pressure gauge, socket set, fuel line disconnect tool
Remove the fuel pump relay and check fuel pressure at the fuel rail.
If pressure is low, relieve fuel system pressure and disconnect the fuel lines.
Remove the fuel pump assembly from the fuel tank and replace it with a new pump.
Reconnect the fuel lines and relay; check for leaks before starting the engine.

4. Inspect and Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench
Remove the ignition coils by unscrewing them from the engine.
Take out the old spark plugs using a spark plug socket.
Install new spark plugs with the correct gap and torque specifications.
Reinstall ignition coils, ensuring they are securely fastened.

5. Inspect Vacuum Hoses

Tools Required: Visual inspection
Check all vacuum hoses for cracks or disconnections.
Replace any damaged hoses with new ones, ensuring a secure fit.
