bad idle

Hello guys....
First off how is everyone doing??? well to get to my problem.... I have a 2002 F-250... 244000 miles...........NO complaints............but I did have to replace all 8 injectors, Valve cover gaskets, glow plus, waterpump..........the scan show the lost of several the machanic replaced all 8..........well it has a bad idle now............the machanic scanned it and it show a miss............the only problem it is show a different cyclinder each time.......(all on the drivers side) we have tried a different wiring harness, ecm, but with no luck...........did I mention when you are driving at 70mph or pulling a load you can not feel a miss..............

Thanks Bo

sounds like a possible bad IDM. what really makes me think that is because all the wiring that normally goes bad has been replaced, there are new injectors, and the biggest give a way is that its all happening on the same bank. and not flipping between banks. hope that helps some.
