sounds more like your temp sensor is shot or you have a loose connection. did u check for a short to ground? did u meter your sensor? did you meter the wire from one end to the other?? if your following what a manual is stating without testing the basics means you should really take it to someone who knows what they’re doing.replace your ecm on a guess without verification?? maybe your temp is spiking??
