Diagnostic Aids
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
The Misfire Current Cyl # / Misfire History Cyl # displays on the scan tool provides information that may be useful in diagnosing DTC P1360. The Misfire Current Cyl # counter may normally display a small amount of activity, typically 0-10 counts. However, the display should not increment steadily. The Misfire History Cyl # counter will display a very large number for the circuits with the largest failure occurrence.
If the condition is intermittent, see INTERMITTENT CONDITIONS under SELF-DIAGNOSTIC SYSTEM.
