I am going to apply the foam when running and believe I will find a way to do this down stream of the MAF. The MAP sensor is right behind the TB and am then worried about that sensor. I guess I will see what happens. The MAP looks to be the cheaper of the 2 to replace. My APF arrived today.
I figured that if I ever used it on my car, I wouldn't bother using it running. If I want it in the cylinders, I'll remove the plugs and spray it in there.
If I want it in the IM, I'll pull the throttle body and fill the IM with it directly.
I know that APF is foam, so it'll be better than things like water or Seafoam, but depending on IM vacuum and vapour flow patterns to evenly distribute a liquid/foam isn't going to work very evenly. For instance I know that water decarbonizing works, but I don't see how you know that you evenly reached all 4,6,8,whatever cylinders through the single brake booster line, for instance. As a matter of fact, I bet you only effectively reach 1 or 2.
