got ecm back plugged it in and started right up. they said it had corrosion in it so they rebuilt it again..... but i never wash inside of truck. now it wont idle and running like crap. Week before ecm went out, 5 months ago, took it on a 300 mile trip and it run perfectly. i guess i messed something up while i was trouble shooting. im 56 years old and never had an issue with any ecm and now 2 in less than a year. GOECM in texas any good?
