All hoses connected & tight on the IC ? I think this is something everyone here has done atleast once.

I'm betting on a clogged fuel filter or possible fuel pump... My TC does this all the time.. but only after sitting for a while.. and it only does it once.. the second time I start the car it runs great.. (Think my problem might be fuel injectors and/or fuel pump (clogged sock anyone?)

It would affect idle but by itself it shouldn't make it stall out. I would certainly fix it or block off that port on the vacuum tree, but I don't think it will completely fix the stalling problem.

still acting up......i got all the old gas out of the tank and put in fresh gas..changed the fuel filter and while it was off i turned the key foward to activate the fuel pump to get the old gas out of the line...i cleaned the spark plugs...checked all the hoses to the intercooler (the rubber boot between the turbo and intercooler was caught up a bit and folded) i thought that was the problem but it wasnt...i pluged up the boost gauge hose...i started her up and she fell flat on her face..then i disconnected the VAM and she ran ok for about 15 minutes (wich was the most i got out of her so far) then when i tried to give it gas it felt very weak and and wouldnt go above 3000 rpm's...i pluged the VAM back in and she fell flat on her face again...then i unplugged the VAM again but this time she fell flat on her face...(maybe the speedometer is messed up but during all this the speedometer was going alittle crazy too)...pretty much everytime i start her up she's acting differently...im thinking it mite be the VAM or it could be somthing with fuel...can aybody think of a good reason she's doing this?

Like Travis said you need to pull the codes. The speedo jumping may indicate some kind of charging issue. I sent you some info for testing the VAF

i changed the altenator and didnt know what to do with the black and white wire...some say the black and white wire isnt hooked up in there t-birds...i didnt hook it up in my car but i dont think thats the problem it seems like its a problem with air or fuel....she hasnt been started in over a year so im thinking somthings corrioded and not reading air or fuel correctly...is there a way i can pull codes at home....or do i have to get ripped off by some mechanic
