Does a 1993 ford ranger have a egr valve?

Yes, a 1993 Ford Ranger is equipped with an EGR (Exhaust Gas Recirculation) valve, as it was a common emission control component in vehicles of that era. The EGR valve helps reduce nitrogen oxide emissions by recirculating a portion of the exhaust gases back into the engine's intake. However, whether a specific Ranger has an EGR valve can depend on the engine type and specific emissions regulations for that model year.
