Summary:
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. |
