[QUOTE="BigAlsPSD, post: 207659, member: 2220"] The IDM code can point to injectors or IDM, have you inspected your wiring harnesses that go under the valve covers(UVCH) they are known to work loose unless they are shimmed or have clips installed, which could be another possibility. I actually 2 weeks ago had an issue with what I thought was a bad IDM all wiring ohmed fine, but #1 would not buzz, come to find out my injectors less than 3 months old, the small screw that retains the armature plate had loosened up and was giving a high to low open code. So I wouldn't rule out injectors. Personally before I threw $450 at a new IDM I would swap with a known good one. The oil discharging from the injectors every time they fire can be observed by running with the valve covers off, and watching the oil come out of the spouts. One not discharging would point to an issue, same as one pissing oil(possible poppet issues) would as well. [/QUOTE]
