Driving normally on freeway last night, check engine light comes on as a start to get of free way and stop at a light my rpm needle, starts jumping up and down 100-200iah rpms! Then stalls, restart car runs fine and check engine light shuts off! So run the scan this is what I got! (Stock throttle body) can it be a MAP sensor?
Those are just stored codes, so the MIL would not be illuminated because of them. I'd clear them and check later to see if they come back. Also, you can click on them and see the frequency and time of occurrence to know if they happened when the car died or were just other "transient" anomalies. My guess - and it's just a wild guess - is a bad (or going bad) CPS.
Fixed I replaced the crank and map sensors -- edit check engine came back on smh, reposted on new post with pictures of the problems 5-28-2017 see new post please to help
