Surging idle makes the car die after new engine combo

[dashapht]

I put new heads, cam, and intake on my car. MAF has a 24# tube in it for my 24# injectors, base idle is set to around 650 so it'll idle around 750 when the car is normal. TPS voltage is set to .987 Is this TPS setting too high? I know it's supposed to be between like .9 and 1v, but is this too close to 1v to work? The car will sometimes start fine and idle ok, but other times will surge like hell and die. It's worse with the a/c on. Also, when driving and i step on the clutch like to coast, it'll drop down sharply and die. Other times when I do that, it'll step down and idle normally. Again, usually worse when the a/c is on. I know there is a part from Ford that is supposed to go between the IAB and the TB to take care of this. Does anyone know the part number and/or what it's called? I followed the procedure in the corral.net tech section to set idle and still no dice. I'm going to try cleaning my IAB unit tomorrow and see how things go. Thanks for any help you offer.
