ok here is what i did.first unscrewed the brake booster line at the driver side. then started the car had my wife rev up the engine and begin to pour, the vaccum will pull in the cleaner no need for a funnel. just put in a steady stream of cleaner you are going into the mainfold don't want to choke it off. while doing this you will get a BUNCH OF WHITE SMOKE out of the tail pipe. once i was finished i turned the car off reattached the brake booster then took it for a ride to get the rest of the smoke out. at first sluggish but began to do better very quick.an as i said i had 2 clogged fuel distributor ports an now they are all opened.
