Car idles really LOW, Then dies...!! Options

[ToYCeLi8]

Well saturday afternoon when i took my out for a spin as i let the car warm up it died on me like always so i gave it a little gas, like i usually do and then let it warm up. But this time it didnt stay on?? I began to idle low and lower until it just shut off on me? It suprised me a lot this time. I thought it was the AFM again (ive been having problems w/ it for a while now), but i didnt worry too much b/c i was going over to sphinx's house and swap AFM to head out to the races . When i switched the AFM it still shut off on me again i got really pissed off by now. I was hoping it was b/c i had messed w/ the timing before to run "decently" with my bad AFM. I just let it go. i just have to keep on giving it a little gas to stay on. Now i put on my new AFM, i tried messing with the timing, tryin to set it back to the way it was before but still NO GO... .

What could it be a vacuum line? FUel?
