ok, well I had to move the bov vacuum line to another point on the manifold as it wasnt getting enough pressure to sense when boost was let off (it was T'd in after three other points lol).

anyway, I moved it to a point on the back of the manifold and T'd right off the manifold in between the charcoal canister and the manifold. Nothing else is on this line.

Then I just put some new hose where I had it previously T'd.

didnt mess with the map sensor vacuum or anything like that.

anyway, since doing this, when I come to a stop it will want to idle at 1500rpm with a rotating surge to 2000rpm but if I blip the throttle, it'll settle back down to around 600-800rpm like normal.

It's been doing this the past 3 days since I moved the vacuum source so I dont think it's the computer relearning as I had the battery unhooked at the same time since I was messing with the steering column and airbag as well.

I think 3 days is MORE than enough time for the computer to relearn idle characteristics. It didnt do this before and I've checked all my vacuum lines and none are off or broken.

any ideas??

I would assume that you have a vac leak somewhere and when you hit the throttle, the IACV is attempting to correct the problem.

As for your vac lines, you should really invest the $40 and get a vac manifold. It will save you a lot of headaches AND clean up your engine bay at the same time.
