2003 Dodge Truck 5.7l 1500 Stumbling and Stalling?

i love it when we get details like this to work with,first off on the timing that it was reading it was a little off,if it was bad cylinder it wold stumble most of the time and also cause a bad hesitation in it,if the temperature sensor goes bad though it will send it back in to open loop mode on the computer and cause a lot of the problems your having on it also,and the one thing i didn't see was a temp reading on it,the readings your getting are more of one that's stuck in open loop mode and due to a bad temp sensor on it,and you wont always get a trouble code for a bad temp sensor on it,the temp sensor though will affect the timing and the other readings your getting off it,so check that and make sure its closed the loop for the computer before you run the test again on it,if its in open loop mode it wont give accurate readings like that,rescan it and see what happens to it,if it were me with that one id replace the map sensor on it and see what happens to it,and also check the temp sensor,that will cause more problems than you think on that truck,good luck on it.
