I concur with this.
Berryman's B12 and a length of vac. hose that fits snug into the 'holes' (there's two of them) on the top of the UIM.
The car will NOT start (and will cut out whilst running) IF you take either of these vac. lines out from the UIM. Hence the need to 'fully then slightly pinch' the line with a vise grips -- to keep the engine running AND yet allow it to 'sip' the cleaner from out of the can too.
Note, B12 _doesn't_ make a lot of smoke ...but if you use "SEAFOAM" --- whoah baby! --- you have been warned!
Make absolutely sure that you re-insert both vac. lines SNUGLY into the UIM -- OTHERWISE the car will not start and/or may run very rough.
If everything works out well ...you WILL notice a difference in the 'stability' of the idle and in the ease of revving etc. etc.
