This document is a Vehicle Emission Control Information (VECI) label from Ford Motor Company for a 1993 model year light-duty truck with the 5.0L (HM) engine, certified for sale in California and OBD I certified. It states that the vehicle uses electronic engine control systems and that idle speed, idle mixture, and ignition timing are not adjustable, referring readers to the Powertrain Control/Emissions Diagnosis Manual. It provides a five-step procedure for checking base ignition timing: turn off the engine, disconnect the in-line SPOUT connector, restart the warmed-up engine, verify timing at 10° BTDC (see shop manual if not), then turn off the engine and reconnect. It specifies SAE 10W-30 oil, API Service SG - Energy Conserving II, spark plug ASF-42C gapped at .052–.056, and the emissions family/equipment code PFM5.8T5HAL9-OC/TWC/AIR/HO2S/EGR/MFI.
