vibration after coil change

[dano]

Hey all...I just changed all the c.o.p.'s on my 05 Expy. That fixed my missing problem at 40-50 mph and 65-80 mph. Now, when it idles down, and like I'm sitting at a traffic light or just slowing down, I notice that there is a vibration in the steering wheel.
I'm pretty much deaf in my right ear and have about 75% to the good in my left, I was thinkin that maybe I knocked off a vacuum line somewhere. Does the low end engine vibration sound like a vacuum issue? It all started after I did the coils. The only other things I did when I did the coils, was to disconnect the battery, and take off the control module (or what ever that is on the passenger side fire wall) and bracket, to allow easier access to the rear two coil packs. Also disconnected most of the fuel injector harnesses to ease the access too.
Thanks for any help.

Sorry, just came across thi thread. Did you ever get this figured out? Sounds a lot like the problem I had and it turned out to be that I knocked the vacuum line loose from the back of the intake manifold when working on cyl#4. The vacuum line is large diameter - maybe 3/4" or 1" and attaches to manifold under windshield. If it's loose, truck will barely idle and run like crap.
