My 420a has a rough idle and code p1390 and a pending code I forget code for too rich, can this be from egr or coil pack? I notice it's worse when coming to a stop fast, I just bought another engine today to build over the winter to put in the car in the spring, just wanna see if I can get it running better while still using it until November
