My Plymouth idles really low and if I make multiple stops it will die out but it starts up every time it has two codes one is an egr failure and the other is the oxygen sensor is there a possible leak or something else that is wrong
There's a lot of different codes related to both of those sensors. We have to know the exact code numbers to know which circuit or system to diagnose. Also need to know the engine size when talking about engine problems. Was the battery recently disconnected?
