Default Question about Ported TBs

I just installed a ported TB on my car, that I bought from an guy on here. Everything is hooked up and I"m throwing no codes but it seems that when I take my car out of gear and let it coast to a stop, like a read light, the RPMs stay higher then they use to. Is this normal or did the porting go too far?

Mine did the same thing. Its normal and it tends to fade over time, but it wouldnt hurt to check for the things cyphur_traq suggested.

Everything seems to be sealed up well after the MAF, I will check agian though, and I don't think the blade is drilled for a larger cam, but I will check that too. Thanks

turn down the set screw to close the blade a little more. its probably open a hair to much and is throwing the iac outta whack

Just to clarify...Turning it down is making less of the screw stick out correct?

I just noticed something else with it. When I come to a stop, a dead stop, it takes maybe a second or two for the idle to drop where it should be normoally. Still the screw? Someone said that I would have to have the computer relearn the "0" for the TPS. Is this the case?
