Visual/Physical Check

Several of the symptom procedures call for a visual/physical inspection. A careful visual/physical inspection can aid in correcting a problem without further checks and can save valuable time. A visual/physical inspection should include the following items:
^ The PCM grounds for being loose, corroded, or in an improper location.
^ The vacuum hoses for splits, kinks, and improper connections. The proper connections are shown on the Vehicle Emission Control Information label. Check the vacuum hoses for any type of leak or restriction. Refer to Emission Hose Routing Diagram.
^ Inspect the air intake ducts for collapsed or damaged areas.
^ Check for air leaks at the throttle body mounting area, the mass air flow (MAF) sensor, and the intake manifold sealing surfaces.
^ Inspect the ignition wires for cracking, hardness, proper routing, and carbon tracking.
^ Inspect the wiring for improper connections, pinches, and cuts.
