91 TA idling problem (NEED HELP)
Hello all. I just bought a 1991 Trans Am with a 305 TPI automatic. It has been sitting for almost a year. It runs almost perfectly when you just barely touch the gas but if you let off completely it does not want to idle. It runs very rough and almost immediately stalls. If you can get it into gear without stalling and drive it down the road it runs fine till you stop at a light or stop sign as it will stall if you don't do a "brakestand" Can someone please help? Where do I start with this problem? Also oddly enough theres no check engine light on at the moment. Thanks so much!

Start with checking sensors such as IAC,TPS, and CTS.
Also check for vac leaks
