I get intermittent P401 on my grand caravan (flex fuel). It comes on then in a day or two disappears.
Other symptoms are erratic idling, which seems to be increasing. I have read other posts that changing egr didn't solve their problem. One posts suggested changing egr solenoid, but I couldn't purchase solenoid anywhere. Is it part of egr.
