Hey guys well i got the new motor into my car and got it running, but it idles so rough and is runnin real rich and i have absolutely no throttle response. I have an explorer upper and lower intake and an explorer throttle body. one issue is that the upper intake has a ton of vac ports underneath...as shown in the following pic. So i need to use a big vac line for the pcv and vacuum tree connection, and charcoal canister. And i need to use small vac imputs for the FPR, EGR, and AC lines. Where should i make these connections and will it matter if they dont come off the same side of the intake as they did with the stocker? Also the explorer TB didnt come with a hose connection on it for the oil filler neck on the valve cover to TB...what am i supposed to do with that...it should be ok for it to just vent into the atmosphere and have no negative effects on how the motor runs??? if anyone can help me out with these vac lines and TB crap it would be greatly appreciated...thanks

Vacuum ports on the manifold aren't specific for one purpose. As long as the hose fits, plug it on an available vacuum port.

The vacuum lines you need are 1 small line for fuel pressure regulator, 1 small line for A/C, 1 small line for EGR system and another small line for the smog pump system. One big line at the back goes to the vacuum tree for the power brake & A/C, one big line goes to the PVC valve. The other big line goes out the front for the carbon canister. In a pinch, one of the small lines can connect to the spare port on the vacuum tree. Cap or plug the remaining lines since they aren't needed.

You should drill the Explorer TB and put the fitting from your stock TB in the Explorer. To remove it from the stocker, just twist it around while pulling - it is just press-fit in there. Drill a hole JUST slightly larger and epoxythe fitting in.
