@kxri318 ,
The only time I've ever seen a 2.9l run rough, it had experienced a head gasket/head or lower intake manifold gasket failure, permitting coolant into the oil.
The only times I've ever seen one stall, it was either an automatic with a failed torque converter or had been driven with a compromised head or coolant leaking into engine by some means.
If misfires I would pursue the fuel system if timing is correct.
If it were only hi idle, I would chase vacuum lines.
SOLVE these issues CONCLUSIVELY, one at a time. I would follow this order:
1) stalling
2) misfire
3) hi idle
Do one thing correctly, then move to the next. Unfortunately, thing don't always fail one at a time and sometimes one failure will usher in another
