Default B18A in '94 DX.. need help with vacuum

ok my idle is totally gheyed. We set the timing correctly (crank to TDC... cam gears to match, etc.). I have the MAP sensor hooked up. The car when it first is started (cold) stumbles a lot... plus when i drive and i shift.. it will hold rev for a bit before dropping. It revs up and down as well. Then after it warms up it seems to fix itself a bit.. however... when i put the car in neutral and i am coasting (still rolling).. the car has that badass camming 'blut blut' sound (it has crower 403s)... the idle is pretty steady and low/normal.. but when i come to a complete stop it resumes revving up and down.

wtf.

is it vacuum? if someone coudl show me a picture of a B18A (PGM-FI stamped on it) intake manifold w/ all the vacuum lines going to the correct places that'd be amazing. Any other help woudl be great.

Another issue.. i have a pretty ghetto 'chiped' ecu (they spelled it wrong on the ecu cover.. yeah seriously) that came with teh swap. I'm pretty sure that has a lot to do with it.. but still.

thanks in advance
