12a. Low Idle Stability (ICP Pressure): Purpose:: Notes

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2005 Ford RV Cutaway, 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.

The purpose of this test is to determine if idle stability or low power is caused by a stuck or dirty injection pressure regulator (IPR) or faulty ICP signal.
