Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool before starting work.

2. Inspect and Clean the IAC Valve

Remove the IAC valve from the throttle body.
Clean the valve and its mounting area using throttle body cleaner and a soft brush.
- Tools Required: Throttle body cleaner, soft brush, socket set
Reinstall the IAC valve and reconnect the electrical connector.

3. Test and Replace the Fuel Pump (if required)

Access the fuel pump by removing the fuel tank or the access panel (if applicable).
Measure fuel pressure with a fuel pressure gauge; compare it to manufacturer specifications (typically 30-45 psi for F-150).
If pressure is low, replace the fuel pump with a new unit.
- Tools Required: Fuel pressure gauge, socket set, safety goggles
Reconnect everything securely and lower the vehicle back down.

4. Check for Vacuum Leaks

Inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner to detect leaks. If the engine idle changes, there is a leak.
Replace damaged hoses as needed.
- Parts Required: Replacement hoses (if needed)

5. Reconnect Battery and Clear Codes

After making repairs, reconnect the battery.
Use the OBD-II scanner to clear any stored error codes and reset the check engine light.
