Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug socket, gap gauge.
Remove the ignition coil connectors.
Using the socket set, remove the spark plugs.
Inspect each spark plug for signs of wear or damage.
If necessary, replace with OEM or equivalent spark plugs, ensuring they are gapped correctly (typically 0.054 inches for F-150).
Reinstall the spark plugs, tightening them to the manufacturer's specified torque (usually around 13 lb-ft).

3. Check and Replace Ignition Coils

Tools Required: Socket set, torque wrench.
Remove the bolts securing the ignition coils and disconnect the electrical connectors.
Inspect the ignition coils for cracks or signs of arcing.
Replace any faulty coils with new ones, ensuring they are seated properly and secured with bolts to the specified torque (typically 7-10 lb-ft).

4. Inspect Exhaust System

Tools Required: Visual inspection tools, possibly a jack and stands.
Inspect the exhaust manifold and connections for any visible cracks or loose bolts.
Tighten any loose connections and replace gaskets if leaks are found.

5. Check Battery and Connections

Tools Required: Multimeter, cleaning brush.
Use a multimeter to test battery voltage (should be around 12.6 volts).
If the battery is low, charge or replace it.
Clean battery terminals and connections to ensure a good electrical connection.
