ah okay......well I guess when the battery is charged again I can do some scanning then with it running.
I did drill a 9/64" hole for the IAC bypass, but haven't been able to test it yet.
I also noticed something funky with the intake. Its a LE ported intake that I goit used......
and the common area the the idle air flows into the spreads it into the cylinders.....has been ported so that it connects to the upper intake area. I'll take a picture tommorrow in the light, but I am guessing that doesn't help the idle quality.

I'm not familiar with what software you are using, but when I used AutoTap the other day after putting in my new motor, Barametric pressure was 29.xx and MAP was reading 9.4 or so, so I had roughly 20 inches of vacuum at idle. I'm not familiar with newer automatics but on older cars it was generally a sign of a vacuum leak when a motor would die when dropping it into gear. Also would explain your no brakes issue as well. Even the LE3 should have vacuum maybe around 8-10 inches at least I would think, but I don't know anyone who has had one so I can be for sure.

I really dont think the brakes is an issue at all........I think its just air in the lines.
without the engine running I can somewhat easily put my foot to the floor with the brakes. With the engine running it goes to the floor with almost no force.
When I do get a chance to run it on thursday I will try autotap

My LE3 383 has about 8 inches of vacuum at idle.
As for getting it to stay running, it sounds like you need to adjust your TB until your IAC counts are down. Don't forget to reset your TPS after.

Unusual for an aggressive cam of any sort to pull more vacuum than the stocker??????

I was thinking the same thing when I read that. The stock motor I just put in pulls around 20.
If you can put your foot to the floor easily with the car off or running then there is something wrong with your brakes in my opinion. When I was bleeding my brakes the other day it was hard as a rock.
