Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Fuel System Inspection

Remove the fuel pump relay from the fuse box.
Connect the fuel pressure gauge to the fuel rail.
Reinstall the relay and turn the ignition to the "ON" position (do not start the engine) to check the pressure. It should be within the manufacturer's specified range (usually around 30-50 psi for F-150).
If pressure is low, consider replacing the fuel pump.

3. Spark Plug and Ignition Coil Replacement

Remove the engine cover if applicable.
Disconnect the electrical connector from each ignition coil.
Using a socket set, unbolt and remove the ignition coils.
Remove the old spark plugs with a spark plug socket.
Install new spark plugs (ensure the gap is set to manufacturer specifications).
Reinstall the ignition coils and reconnect the electrical connectors.

4. Air Filter Replacement

Locate the air filter housing.
Unclip or unbolt the housing to access the air filter.
Remove the old air filter and clean any debris from the housing.
Install a new air filter, ensuring it is seated properly.

5. Exhaust System Inspection

Inspect the exhaust system visually for any signs of damage or restrictions.
If the catalytic converter is suspected of being clogged, it may require replacement. Use a jack and jack stands to safely lift the vehicle and access the exhaust.
