Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Allow the engine to cool before working on any components.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and clean the housing.
Install a new air filter, ensuring it is seated properly.
Reattach the air filter housing cover and tighten to specifications.

3. Check and Replace Spark Plugs

Remove the ignition coil covers using a socket set.
Disconnect the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Check the gap on new spark plugs and install them with the correct torque (typically around 13 ft-lbs).
Reinstall the ignition coils and covers.

4. Inspect and Clean Throttle Body

Remove the throttle body from the intake manifold using a socket set.
Use throttle body cleaner to remove carbon buildup inside the throttle body.
Reinstall the throttle body and tighten to manufacturer specifications.

5. Test Fuel Pressure

Connect the fuel pressure gauge to the fuel rail test port.
Start the engine and observe the pressure reading; it should match manufacturer specifications.
If pressure is low, replace the fuel pump and/or filter.
