There is a tiny hose on the fuel pressure regulator that tends to crack over time.
It attaches to the under side of the intake manifold and its very possible a leak in that tube would not be detected. ( if this is the one the runs from under the throttle body to down by the drive side wheel well, its been replaced and it was a pain in the ass to do so)
Inspect, check, clean, the throttle position sensor on the side of the throttle body.
(the throttle position sensor has been cleaned as has the inside of the throttle body and passages.)
Inspect, check, and find out if your intake manifold is leaking.
once my engine is cool, i will yank the crap outa that thing
