WARNING: This page is about a different car, the 1996 Mercury Grand Marquis and 1996 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
Perform PCM self-diagnostics. See appropriate article in the ENGINE PERFORMANCE section. If codes are set, repair as necessary. Go to TEST A. If no codes are set, wiggle Tan/Orange wire and Pink/Light Blue wire between EATC module connector and data link connector while checking continuity. Repair as necessary.
