Anybody ever came across that engine code? Witch is "internal control module memory check sum err" my truck kinda spits sputters and pops Expessially when it's cold and it like to big down a bit and kid of jump when I'm driving. I googled the code and they said it could be a lot of things most likely the Powertrain control module(PCM) needs to be replaced. Anybody have any thoughts on it?
