I just fixed my focus for a similar issue, eventually I found 2 vaccum leaks, one vac line wad a solid hole, because the tube was dry rotted and cracked, replaced that, but then the studder was still there randomly, eventually I was able to find that the valve cover breather was off the valve cover and enough gook had settled on the vac line to make it rub and wore through, but the grease was caked on thick enough that it would seal the vac line causing it to be an intermittent problem.
