You need to run your engine at about 2500 to 3000 RPM, let the vacuum line sit in the can until it's gone. Modulate the RPM so that it doesn't die, but don't redline it either. You WILL get a large cloud out of it, but that's normal. After the can empties, turn the car off. Let it sit for about 10 to 15 minutes and then start it up and run the piss out of it until it stops smoking. It's also HIGHLY recommended that you change your oil and spark plugs afterwords. It made a world of difference on my DSM, my Mirage, and my Contour (before I sold it).





btw i didn't mean let it die immediately...you will have to give it enough throttle to keep it running long enough for it to suck in the 1/3 or half of the can,but after that it doesn't matter if you let it die or shut it off yourself,what's the difference?????it has to be shut off one way or another...

and actually changing your plugs is totally unnecessary.....what would be the point????????????????really oil doesn't have to be changed either for that matter(but it wouldn't hurt)..but plugs are totally unnecessary...the carbon that is being cleaned out is being burnt off hence the smoke...the smoke is the carbon being cleaned out...and if you add it to the oil then yes you should change it,but if not i wouldn't bother unless it was close to time for a change...

i am telling you this because i have done alot of research on this on the mustang boards....i've read probably over 100 cases of this being done and the plug changing afterward is totally unnecessary,and that comes from a few guys who bulid engines for a living,and know their stuff... and one guy who is a gm mechanic,who's shop does this on a daily basis apparently caddies and other gm's seem to get a premature bad carbon buildup....there is a very long thread on stangnet about this topic,and ALL of the guys in the know deemed it unnecessary to change plugs....
