Visual Inspection

Visually inspect all electrical wiring. Look for chafed, stretched, cut or pinched wiring. Ensure electrical connectors and connections fit tightly and are not corroded. Ensure vacuum hoses are properly routed and are not pinched or cut. See the VACUUM DIAGRAMS article in this section to verify routing and connections (if necessary). See below. Inspect the air induction system for possible vacuum leaks.
