Idle problem

[dmtunc99]

I just got my 95 gs-t today, so I don't know much about it yet. The first half of the drive home it was all good, but towards 30 mins til I got home, I was having big problems. Whenever I put in the clutch and the rpm's drop, the engine just shuts off. Also when I restart it and try and put it back in gear I have to give it a lot more gas than usual, or it just shuts off again. I've noticed a weird hissing type sound from underneath the car that wasn't there when I first started driving it as well. Any ideas would be greatly appreciated, I'm having trouble just getting it out of my driveway.

Ok I just took it out to drive it around the neighborhood after letting it cool off for maybe 20 mins or so, and it ran ok, but there is still the weird hissing sound from underneath the car that I never heard before.

could be a boost leak, sounds to me like unmetered air is getting in. do a search for "boost leaks" "unmetered air" and vaccum leaks" on here.
