i have a 2005 honda accord ex coupe v6 3.0, i have replaced spark plug tube seals, spark plugs and injectors and did the value cover gaskets and it still idles rough in drive when stopped, does the same thing in reverse and in neutral it idles most of the time? any thoughts? its still throwing up code P0158 saying its the downstream o2 sensor but it wasnt bad yesterday? thanks for viewing my thread.
