[QUOTE="old man dave, post: 1311431, member: 1009"] The UVCH pair of injectors would be 2&4, so that would seem to be a bad UVCH harness. The usual bad IDM failure would be one whole bank at a time, not 2&4. Try a Ford UVCH harness this time, Dormans are known to have a wiring error in them. Also check the engine harness to valve cover to UVCH connections for burnt pins/broken wiring on the 2&4 wiring string. [/QUOTE]
