1995 Lesbre stalling intermittently

[rpolk]

My 1995 LeSabre with 60,000 miles began stalling recently.
Usually while idling, occasionally upon accelerating. Usually restarts without
delay, occasional extended cranking experienced.
Idle becomes slightly erratic prior to stall.
No dtc's but datastream on scan tool (monitor 4000 enhanced) reads IAT about 20 degrees F lower than the ambient temperature . I am just wondering if that could indicate a problem with pcm. I have been trying to solve this issue and would appreciate any insight.

The iat would not cause stalling, the maf can do this, a stuck egr, dirty thottle body, lazy iac, are some issues here.
