[QUOTE="dmd, post: 1499127, member: 1848"] I went through this with a intermittently faulty modified Swamps IDM that I sent to them and they tested as good... After replacing almost everything after the IDM I called them asking if any way the testing could have missed it. They agreed that testing isn't always 100%.... UGH.. replaced the IDM with a known good one and it has been fine for months now... Wish they had told me that in the beginning. We did find some burnt wires and had to replace the pigtail and under the valve cover wiring on one side, and the injectors had over 200K on them so it wasn't a complete waste. Mine would shutdown the drivers side injectors so it would run really bad, then it would just go away for weeks. Then would come back randomly.. Whenever it happened and I would get ready to find the issue it would go away... Shop drove it for weeks for around town for parts pickup and it ran great.. Injector wiring and IDM problems can be difficult. [/QUOTE]
