Idle switch? Bad Gas? or POS?

Hello all. I recently bought a G20 fell in love with it hooked it up within the 1st week. Then all of a sudden after a little road trip. I stall at a red light, i didnt think much of it till every 5 outa 6 stops i stalled. not knowing what the problem was i checked the battery and many simple things yet.. no fix. I was thinking maybe the idle switch needs to be adjusted or somthing but i cant find it.. its a 93 automatic. can anyone helpme before i take this thing to get hooked up to the machine that will cost me 70 dallors+. Thanks P.S i found some really HOT kits for these G20's....

OH yeah i also get this happends right away when i start my car unless i give gas or anytime i slow down.

Search around www.g20.net I believe that has happened to others.
