Just checking in on the road. Thanks for the suggestions guys!
I'll try the carb cleaner trick. I don't think I have a vacuum leak though. Idle is very steady when cold, and when it warms up there is only the slightest hint that its misfiring. When I've had vacuum leaks before the idle is effected a lot more and there has usually been surging. Maybe this isn't always the case though?
The plugs are new with all the work I've done. I've even swapped back to the old plugs and back to the new ones, and moved them around to make sure its not specific ones (did the same with the coil packs).
The grounds have been cleaned as I went through the work I've done. I can double check that though.
Thanks again for the ideas.
I'm about out of them myself!
