Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Raise the vehicle if inspecting components underneath.

2. Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing.
Take out the old air filter and inspect for dirt and debris.
Install a new air filter, ensuring it is seated properly.
Reassemble the air filter housing and secure it.

3. Inspect and Replace Spark Plugs

Remove the ignition coil covers if applicable.
Disconnect the ignition coils and remove them using a socket set.
Take out the old spark plugs using a spark plug socket.
Check the gap on new spark plugs and install them to manufacturer's specifications (typically 0.054 inches for most Ford engines).
Reinstall the ignition coils and covers.

4. Check and Replace Fuel Filter

Locate the fuel filter; it may be in-line or integrated with the fuel pump.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter, using caution due to residual fuel.
Replace the old filter with a new one, ensuring correct orientation.
Reconnect the fuel lines securely.

5. Throttle Body Cleaning

Remove the throttle body, disconnecting any sensors and hoses attached to it.
Use throttle body cleaner to clean the inside of the throttle body, removing carbon buildup.
Reinstall the throttle body and reconnect all components.
