U simply unplug the PCV vacuum line, clean the end of it off with a shop rag, start the vehicle, & dip the end of that hose into the can of Seafoam. Sometimes u have to rev the throttle up some to keep the engine from dieing if it is really carboned up. Just poor any left over Seafoam into ur gas tank & drive the heck out of her (safely) until she stops smoking.
Keep us posted. =o)
