Ford Fairmont (1978) – 78V203000
Vehicle recall defect – The Involved Vehicles Contain Emission Control Systems That Utilize A Pulse Air Reed Valve To Permit Air Flow From The Air Cleaner To The Exhaust Manifold On Negative Pressure Pulsations. These Reed Valves May Fail Under Cold Weather Conditions, Causing A Backflow Of Exhaust Gas Into The Air Cleaner And Fuel InduCTIon System On Positive Exhaust Pulses. This Causes An Overly Rich Air/Fuel Mixture, Reduced Fuel Economy And Reduced Engine Performance. Continued Vehicle Operation May Result In Engine Stalling Or Overheating Of The Exhaust System.
