Sounds like it could be map sensor but that wouldn't explain the sound, I have the same I'll take a look and see if I can help

This might sound odd, but I'm just going to chime in here. My coolant sensor was going bad (actually wires running to the plug). With that the Z would always run rich (PCM thinks its still cold so pumps more fuel to warm it up). So after re-splicing the harness and putting in a new sensor and plug it reads properly and when I give it has while parked in park or mutual it doesn't stall or cut off anymore. Not sure if that's your exact problem just thought it might be a bit of knowledge for ya.

Got it stuck. It's still stuck. It's so stuck I could call insurance and say it was stolen and no one would ever know. It's so stuck I don't know anyone with a capable enough 4x4 to even to to where I got stuck to winch or yank me out.

Check this out. I know there r a couple vacuum hoses on the back of ur block around the transmission bell housing. Between the block and firewall. But it would have to be a huge vacuum leak to stall a 5.2. Sound more like to me. That ur catalytic converter is plugged. If ur engine can't breath it will stall out. It will create a vacuum like noise around ur dash area. Noise travels throughout a zj. Any lights on the cluster? Funny smell. Does it start up fine? Pm me with any questions.
