Target Training Systems Quick-Check Guide covering TPS (Throttle Position Sensor) and minimum idle specifications for 1981–1987 carbureted, throttle body injection, and port fuel injection vehicles. Designed as a quick-reference shop guide for technicians and mechanics; note that the title page appears to contain a typographical error showing "1981 to 1887." Guide is in good vintage condition with light age-related wear, while the protective plastic binder cover shows noticeable scuffs and scratches from use.
