Does it shoot black smoke or anything? Are you a/c? The same code came on for me and for some reason I replaced my map and then it was good

Nope no black smoke or nothing. Just after I start coming to a stop and shifting it's fine until I come to the complete stop where it just shoots down . I'll try the map sensor tomorrow then
