engine stalling?!?

['03snkbt]

have been doing some research thru the threads and came across one the said, " if your car is stalling out in idle, you need to clean out your IAC and MAF ". so last pm cleaned out all of that black soot and ran like a champ. this am totally different story. car just wants to die everytime its in N and idling.
AFR reading good and LB1 reads good also. car just sounds like being choked out for some reason. any ideas of what to attempt next?!? :shrug:

Carefully inspect your PCV hoses and vacuum lines.

A propane torch with the gas turned on but unlit. Engine idling, nozzle of torch following vacuum lines and connections and all intake gaskets.

If/when the idle rises up the leak is where the nozzle is pointing.:beer:
