The engine on occasions will stop when approaching traffic light to stop and when slowing down to take a corner.. The engine seems to run OK but now and again appears to miss fire

The issued started when my car failed to turned over but immediately died one morning. It started on a third try and I drove to the store. When I put it into park however, the idle became erratic. On my way home, I noticed that occassionally the idle would jump up about 1000 rpms while driving. I smelled the burning and knew something was wrong. The check engine light came on and it was the idle air control (IAC). In addition, a chip in my ECM (ECU) had burned up. The chip was in 2 pieces when we took the ECM out and looked at it.

Car would start but die immediately when not pressing the gas pedal. If you slightly press it will run just fine. I cleaned the mass air flow sensor . Then changed the IAC . I first removed and checked the ECU and didn't see any noticeable issues or dark spots. Put everything back together and still no idle. I was told it needed to be programmed or relearn. We tried repeatedly the manual process , crazy process , used a snap on analyzer and followed the prompts as well. Still no idle.
