This is my first post on this platform so if there is anything i need to do different please let me know. A few month ago i bought my first 5.0 and am currently having a wrench light issue. I would consider myself somewhat knowledgeable with cars but i still have much to learn. In the past 2-3 weeks i have had this wrench light come on with no indication of what it is, once while i was just cruising at interstate speeds, and twice during WOT. The car loses all power and goes into what seems...

New to my 5.0, wrench light question
