The poster mentioned his buddy thought it might be an intake gskt leak, I don't agree, with the info he's supplied.

If someone takes what you know for sure, and info from someone else, they might put 2&2 together and come up with a solution for their problem.

FWIW, I recall my 3.0 starting and stalling as soon as the keyswitch was released from the crank position without an afm signal/flapper door movement, likely gettin fuel from the cold start inj.
