Just for grins, pull off and plug the vacuum hose fitting to the power brake unit on the manifold. You may be getting a massive vacuum leak in the brakes. See if it runs any better.

Okay... replaced the ASD relay and it was still doing it, so i started checking the wiring going to the PCM and found a pink/white wire cut in half.. soldered it back together, taped it up and viola!!! Running great again!!

Ah, jumped off the stove and into the fire, huh? Good luck with that hemi. Is that one of those variable displacement nightmares? The major design fault with the hemi is the draining back oil doesn't fall on the cam lobes so they starve for lubrication. This causes the roller lifters to disintegrate.

Turned out to simply be an air hose... the one going from engine to the intake... had a rip in it and on the way back home from work, it ended up coming disconnected and i was hearing the air slurping... pulled into a parking lot, wrapped it with electrical tape and she.is once again running like a champ...
What air hose was it ??
