Visual/Physical Inspection

Several of the symptom procedures call for a careful visual and physical inspection. This can lead to correcting a condition without further tests and can save valuable time. This inspection should include the following areas:

• Inspect all vacuum hoses for pinches, cuts, disconnections, and proper routing.
• Inspect hoses that are difficult to see behind other components.
• Inspect all wires in the engine compartment for proper connections, burned or chafed spots, pinched wires, contact with sharp edges or contact with hot exhaust manifolds or pipes.
