Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt and obstructions.
Install a new air filter, ensuring it fits snugly in place.
Reattach the air filter housing cover and secure it.

3. Fuel Pressure Test and Replace Fuel Filter (if needed)

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition key to the "on" position without starting the engine to check the pressure.
Compare the reading with manufacturer specifications; if low, replace the fuel filter.
To replace the fuel filter, locate it along the fuel line, relieve fuel system pressure, disconnect the fuel lines, and replace the filter with a new one.

4. Clean Throttle Body

Remove the throttle body from the intake manifold by disconnecting the electrical connector and loosening the mounting bolts.
Use throttle body cleaner and a soft brush to clean the throttle plate and inside walls.
Reinstall the throttle body, ensuring a proper seal and reconnecting the electrical connector.

5. Inspect and Replace Spark Plugs

Remove the ignition coil from the spark plug by disconnecting the electrical connector and loosening the retaining bolts.
Use a spark plug socket to remove the old spark plug and inspect it for wear.
Install new spark plugs according to the manufacturer's gap specifications, ensuring they are torqued to the recommended value.
Reattach the ignition coil.
