'00 4.0 5-speed starts then stalls out

My '00 TJ with 115,000 started acting funky today. It would turn over, fire up and then immediately stall. If I kept feathering the gas, it would continue to run but as soon as I let off the gas, it stalled right back out.

I've read some other posts etc. and none really narrow down the problem, just open up a whole can of worms. I'm taking it to autozone tomorrow to see if any codes pop up and I'm going to order up 2 new keys. Apparently the chip in my one key could be junk now. I'm also going to remove the aftermarket (viper) anti-theft system the PO had installed. I don't use it and apparently that could also be the issue. I ended up getting her going fine and the issue hasn't come back (fingers crossed) the past 3 or 4 times I started her up.

From what I've read, it could be the PCM, crankshaft positioning monitor (?).... Anyone have any suggestions.

Thanks,
Dean

So after further research, it seems like I might have to clean out my throttle body. I'm also going to be replacing the battery seeing as I think I'm long overdue for that anyhow.
