more problems...

so yesterday i fixed my fuel pressure problems with a new aeromotive FPR so now it stay at 40 and rises when there is little boost. now on to the problem. i hooked up the laptop and noticed it wasnt reading vaccuum aswell as water temp. so i remembered that the one side of the TII manifold doesnt have a constant vacuum. i switched it the other side. started the car and it was seeing vacuum. now this is where it gets confusing. after i messed around with the temp sensor in the water pump it also showed up that it was reading but at 124C im guessing cause the housing was that temp. anyway i start the car everything is working and was reading 12:1 afr like how i was told it would, idle was 900, temp was slowly going down. then it gets weird i couldnt rev it at all. i would push on the throttle, it leans out and now my temp sensor isnt reading? i changed the sensor 3 times and same problem. i switched back the map vacuum line and it would rev... i will be sending the car to a local microtech shop to get looked at, but anyones input would help.
Thanks!

PS. this is in a 1st gen using a 12AT cover and 1st gen water pump on a jdm 13BT.

UPDATE!!!

Today i got the car to cold start by turning the screw on the butterflys so its closed. second i hooked up the map sensor to a different spot then behind the throttle body( the vacuum nipple inbetween the primary oil injectors). found out that there is a hickup between 1000-1500, it goes lean and backfires. once you are able to get it pass that point it will rev. now im only pulling 10inHG at idle so i thought lets take off the intercooler pipe right before the throttle body. at idle the engine pulled 15-20inHG and the hickup from 1000-1500 was still there but wasnt bad. now im only reving to 3500 due to a fresh motor. i have vids on my camera phone but you will see what i mean
