3.Visually inspect for obvious signs of mechanical and electrical damage.

4.Exercise the wiring and connectors of the components for obvious problems due to looseness, corrosion, or other damage. This must be done while the engine is fully warmed and the system controls are activated.
5.Check the vacuum lines and connections for looseness, pinching, leakage, splitting, blockage, or other damage.
6.If a vacuum line or orifice (restrictor) blockage is suspected, correct the cause before proceeding to the next step.
