- Start engine and run at 3000 RPM with no loads and transmission in Park or Neutral, until radiator fan comes on. Allow engine to idle. Disconnect vacuum hose from air cleaner housing. See Fig 1. Measure vacuum at vacuum hose while increasing and decreasing engine speed.
- If vacuum changes with engine speed, system is operating properly at this time. If vacuum does not change, check vacuum hoses for correct routing, leaks, breaks or clogging. See Fig 1. If vacuum hoses are okay, check FIA control valve for cracks or damage. Repair or replace components as necessary.
