Hi All, I just put my Plymouth Voyager on the computer and found I had a code of EXHAUST GAS RECIRCULATION FLOW INSUFFICIENT DETECTED. STFT BANK 1 -4.6% LTFT BANK 1 14% INTAKE MANIFOLD PRESSURE 13.5 in. hg. Does anyone know how many EGR valves their are on this vehicle? Any idea where I should start looking? Thanks in advance, Blair
