Just about to use Seafoam for the first time and instructions state that it should be introduced directly into the engine through a vacuum line that serves all cylinders. For a Crossfire motor (LU5), does the vacuum line that connects to the MAP sensor serve all cylinders or is there another one that I need to use?

I would divide up the can, half would go into each tbi unit. Use the ports at the base, don't use the map sensor hose, the engine won't run without it.

i always just use the brake booster hose.

If you're interested in cleaning injectors and cylinders you could put it in the gas. easy and worked great for me. Engine improved a huge amount after two or tankfuls.

Thanks for the good advice. I decided to introduce Seafoam into each TBI through the port at the lower right of each unit and also added it to the gas. Used vacuum tubing and a t-fitting so that the TBIs would be fed evenly. (see picture) Went to a remote area last night, and it worked as advertised. Drove the car to work today and it's a real nice improvement. Will continue to use in the gas for the next few fill-ups. Much appreciated.
