VISUAL INSPECTION
Perform a visual inspection of all electrical wiring. Look for chafed, stretched, cut or pinched wiring. Inspect electrical connectors and connections for tight fit and corrosion. Repair as necessary. Ensure all vacuum hoses are properly routed, and are not cut or pinched. See VACUUM DIAGRAMS article in the ENGINE PERFORMANCE Section to verify routing and connections (if necessary). Inspect air induction system for possible vacuum leaks after the airflow meter.
Spark Test
Check for spark at coil wire and each spark plug wire, using a spark tester. Check spark plug wire resistance on suspect wires. Resistance should be 2000-4000 ohms. Coil wire resistance should be 500-1500 ohms.
