Red lightning bolt?

[LoneWolf3574]

OK so I have a 04 ram 2500 4x4 with the 5.7 hemi in it I have gotten that lighting bolt as well but never while driving. Now I replaced the battery it was a 16' battery (don't know how it was starting every day but it did) I changed the throttle body and it did help now I still get that light but only when idling for a bit and I get the barometric sensor code that come with it that is a new sensor now I want to know will a MAP sensor help with this problem.

There is a procedure for programming/setting the new throttle body. I don't remember what it is, but I'm sure it is on YouTube.
