Computed Timing Check
WARNING: This page is about a different car, the 1995 Mercury Grand Marquis, 1995 Mercury Cougar, 1995 Lincoln Town Car, 1995 Ford Thunderbird, and 1995 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
Ensure all accessories are off and engine is at normal operating temperature. Disconnect SPOUT connector. Connect timing light. Using ignition switch, start engine. Ignition timing should be approximately 10 degrees BTDC (base timing). Reconnect SPOUT connector. Timing should advance from base timing. If timing is not as specified, check for causes of incorrect timing such as damaged Crankshaft Position (CKP) sensor. For additional procedure, see IGNITION CHECKS in the BASIC TESTING - 4.6L article.
