Why couldn't AutoZone pull my code for my 1994 oldsmoblie cutlass suprmeme.?

AutoZone likely couldn't pull the code for your 1994 Oldsmobile Cutlass Supreme because that model predates the OBD-II standard, which was implemented in 1996. Instead, it uses the older OBD-I system, which requires a specific diagnostic tool that many auto parts stores do not have. Additionally, if the vehicle's check engine light is not illuminated, there may not be any codes to retrieve.
